Baseball[edit]

A view of the playing field at Fenway Park in Boston.
Baseball is played in a quadrant of fair territory between foul lines. The official minimum distance from home plate to the nearest fence, stand or other obstruction is[1] 250 feet (76.2 m), and the recommended distances are at least 325 feet (99 m) along the foul lines and 400 feet (120 m) in center field.[2] This produces a recommended fair territory field area just over 100,000 square feet (9,300 m2). MostMajor League Baseball parks have fair territory areas in the range of 110,000 to 120,000 square feet (10,000 to 11,000 m2).[3]

Cricket[edit]

In contrast, Test and One Day International cricket is played on a field with a minimum width of 420 feet (128.0 m) and length 426 feet (129.8 m), giving a minimum area of 140,500 square feet (13,050 m2), assuming an elliptical shape. However the shape of a cricket ground is not fixed. Test grounds around the world are typically 450 by 500 feet (140 by 150 m), an area of 175,000 square feet (16,300 m2), and range up to the Melbourne Cricket Ground at 479 by 561 feet (146.0 by 171.0 m) or 270,000 square feet (25,000 m2).

Consequences[edit]

Discounting the pitcher/bowler and catcher/wicket-keeper, this means Major League Baseball fielders must cover an average of approximately 16,500 square feet (1,530 m2) per fielder, while Test cricketers cover 19,500 square feet (1,810 m2) per fielder. That average is misleading because the difference between area covered on the parts of outfielders (on the one hand) and infielders (on the other), is vast. In baseball, infielders cover a small area in which the ball moves very fast, while three outfielders must cover an area that encompasses a much greater proportion of the playing surface. Something similar — if not quite as pronounced — is true in cricket. In practice, fielders in both sports cover variable amounts of territory, with outfielders potentially having to run much farther to field a ball than infielders do.
Another consequence is that the maximum distance from the batsman in cricket to the boundary is far smaller than the maximum distance from the batter in baseball and the outfield wall. Since the pitch in cricket lies at the centre of the field, a ball can often be driven beyond the boundary at even the greatest distance from the pitch by a blow that travels around 275 feet (83.8 m). By contrast, a home run to 'deep center' in baseball must travel more than 400 feet (121.9 m). This means that outfielders in baseball must frequently cover considerably greater distances than those fielding a ball in cricket. When hit squarely in baseball the ball leaves the bat at a higher velocity, and travels farther, than in cricket.
A batsman in cricket has a greater variety of strokes he can play, due to the lack of fouls and strikes; this combined with the shape of the field means he can play shots in any direction, including directly behind him.

Bowling/Pitching distance[edit]

In cricket, the distance between the two wickets that the batsmen defend is 22 yards (20.1 m), 66 feet, or 1 chain (4 rods) in the old English system of measurement. The pitch is the 10-foot wide rectangular area between the wickets.[4] In baseball, the pitcher must deliver from a rubber slab (officially called the "pitcher's plate" and typically called "the mound") whose front is 60.5 feet (18.4 m) from the point of home plate (officially called "home plate" and often simply "home"). Before the advent of the pitcher's mound and the rubber, the pitcher threw from within a rectangular "pitcher's box". There was a large rectangular dirt area, between the pitcher's box and the batting areas around home, which resembled the cricket pitch.
In cricket, the striker's end stumps and the bowling crease are 66 feet (20.12 m) apart. The popping creases are 4 feet (1.22 m) in front of the stumps and thus are 58 feet (17.7 m) apart. The bowler's release point could be perhaps 1 foot (0.30 m) beyond his popping crease. The batsman tends to "take guard" or "block" on the popping crease, i.e. he stands 4 feet (1.22 m) in front of his stumps. That nets to a typical distances of about 57 feet (17.4 m) between delivery point and bat. In baseball, the pitcher's release point could be about 55 feet (16.8 m) depending on his delivery style, but the batter also tends to stand back or "deep" in the batter's box, to maximize his time to "look the ball over", up to 2 feet (0.61 m) farther from the pitching rubber than the point of home plate is. Thus the horizontal distance, from release of the ball by the pitcher/bowler to its arrival at the batter/batsman is similar in both sports. However, the ball usually travels further in cricket as it normally bounces off the ground first, adding a significant vertical component to the total distance traveled.[5]

Play[edit]

Fielding[edit]

The main difference in fielding in the two sports is that even though a cricket ball is harder and heavier than a baseball, the fielders in cricket are more restricted in the use of protection for the hands. The only fielders who can wear protective gear are the wicket-keeper, who is allowed to wear padded gloves as well as leg guards and a box; and fieldsmen in close-in positions such as silly point and short leg, who may wear shinpads, boxes and helmets but they are still not allowed to wear any gloves. In baseball, catchers and first basemen normally wear mitts, which have no fingers and are specially designed for each position respectively. The other fielders wear gloves with fingers. (Note that early baseball was also played bare-handed; gloves were adopted in the later 19th Century.) This means that the risk of hand injury due the impact of the ball is far higher in cricket. Also, especially in Test cricket, it is common for several fielders to be stationed close to the bat (slips, short leg, silly point and similar positions) since the likelihood of dismissing a batsman off a catch is higher. Catching at these positions require exceptional reflexes, skill and courage, associated with bare-handed catching of a hard ball traveling at up to 100 miles per hour (160 km/h), with reaction times of the order of 0.2 seconds.
Baseball games have far lower scores than cricket matches. The largest combined runs total in a single game in the history of Major League Baseball is 49, whereas first-class cricket matches, including Tests, have produced combined totals from both innings of over a thousand runs.
For a more direct comparison, matches in Twenty20 cricket, a form of limited overs cricket in which games last about as long in time as a regulation baseball game, regularly produce combined run totals of 300 or more, with the all-time record being 469. Each run in a baseball game is roughly seventy-five times the magnitude of a run in a Test cricket match; therefore moments of poor pitching and individual fielding mistakes are much more costly. A baseball player who is a good batter, but who is not a competent fielder, will not play regularly, or only in the designated hitter position in leagues that use it.

Baseball players often need to throw immediately after catching the struck ball (for example, the double play), while this is unnecessary in cricket as the ball is deemed "dead" when a dismissal takes place. Hence, fielders in cricket have a greater incentive to dive and take a catch due to the fact that a run out is generally much harder to achieve.
The configuration of the baseball diamond effectively bars left-handers from the fielding positions that make throwing to first base a primary responsibility. Right-handers can throw to their left — i.e., toward first base — with much greater ease than can left-handers. So in practical terms, all second basemen, shortstops, and third basemen are right-handed. Left-handed catchers are also exceedingly rare; while the reasons appear to be primarily cultural, handling bunts up the third-base line and throws on plays at home pose particular obstacles to left-handed catchers.[6][7]
While most throws a first baseman must make go to the right, which a left-hander can generally accomplish with greater speed and fluency, this is a relatively small factor in the advantage for left-handed first baseman. More important advantages are related to the position of a left-handed first baseman with respect to the base. First, a left-handed first baseman has an advantage over his right-handed counterpart when catching a pickoff throw from the pitcher—when a first baseman is in pickoff position, standing in front of the bag, the left-hander can catch the ball and make a tag without having to move his arm across his body. (See the picture in the Strategy over the course of the game section below for the standard pickoff position with a right-handed first baseman.) Second, because the first baseman starts most plays with his left leg closer to the base, the left-hander does not have to make a half-pivot in order to get into the correct position to stretch out for a throw. For these reasons, left-handed throwers are far more common at first base than in the general population of baseball players. In contrast, cricket is fielded in the round: the handedness of the fielder in any given position is of far less consequence due to the priority being placed on catching rather than throwing coupled with the fact that the batsmen are running in opposite directions, and both left-handed and right-handed throwers are found in all parts of the field.

Body contact between runner and fielder is frequent in baseball, particularly at home plate. This is driven to a large extent by the manner in which a runner is put out. In both sports, rules prohibit interfering with runners. However, in baseball, the runner himself (or the base he is advancing to, if forced) must be tagged by a fielder holding the ball, in order to be put out. The catcher awaiting a throw will often stand between the plate and the runner. Once he catches it, the runner might try to go around the catcher, or he might simply bowl the catcher over, if he thinks he can dislodge the ball by such contact; and if the catcher does not have the ball, the runner may still bowl the catcher over, which is considered fair because by rule a fielder without a ball cannot impede a runner. By contrast, in cricket, the stumps are the target for "tagging" rather than the runner. No contact of the runners is either necessary or allowed. Contact between opposing sides is rare, and is usually not deliberate. Violent contact between players was once even greater in baseball, as before theKnickerbocker Rules it was permitted in some versions of the game to literally "throw out" a runner by hitting him (or "soaking" him) with a thrown ball (in lieu of hitting a base or stake that would equate to cricket's wickets). This rule still exists in some versions of the baseball variant called kickball, which is played with a soccer ball and thus is much less injurious. Except when played batting in a hands-down position, kickball also calls for literal "bowling" of the ball, underhand, as with the old rules of both cricket and baseball. "All 'round hands down" kickball leagues exist, but in most of these, the ball is pitched with the face or shoulders.

Batting[edit]

Main articles: Batting (cricket)Batting (baseball)
There are many possibilities for a batsman in cricket. (The shots shown are for a right-handed batsman.)
One of the main differences between baseball and Test cricket is the primary intent of the batsman. Usually, in Test cricket, wickets come at a far higher premium, since survival is of primary importance. While nine innings per side are played in a baseball game within a few hours, only two per side are played in Test cricket over five days (thirty hours), so the cost of a dismissal is far higher in cricket. It should be kept in mind that a batsman in cricket is not obligated to take a run after striking the ball nor is there any penalty for swinging at the ball and missing unless it hits the stumps, and there is no limit to the number of deliveries a batsman can face; a batsman with the concentration and technical ability to bat for several hours without being dismissed is able to do. By contrast, in baseball a batsman takes a serious penalty (a "strike") if he swings and misses, three strikes result in an out, and if the batsman hits he must run. This contrast means that in cricket, unlike baseball, the quality of a batsman's defensive game and footwork (because unlike baseball batters cricket batsmen aren't required to keep their back foot grounded) are of the utmost importance. The nuances of batting technique are also greater in cricket, since the interplays between bowling variations, field placements and scoring strengths are more dynamic. Since cricket is played over an extended duration, it gives the bowler and the fielding captain time to "work over" a batsman. Thus, cricket batting requires a very tight technique and the ability to withstand sustained examinations.
The area for legal deliveries is much larger in Cricket than it is in baseball, overlapping the batsman's entire body. Deliveries that reach the batsmen at rib or shoulder height are not illegal, and quite common. Depending on the version of the game, a greater or fewer number of deliveries can be bowled to reach the batsmen at throat or head level. Any fear or hesitation can lead to a batsman playing a poor shot which may result in him giving away his wicket (being dismissed).
Since the cricket bat is wide and flat, while the baseball bat is narrow and round, on the whole cricket batsmen find it easier to hit and direct the ball than baseball batters, resulting in much greater number of runs being scored in a cricket match. While bowlers can influence the ability of the batsmen to do so, perhaps the most famous episode being the Bodyline tactic, cricket batsmen are able to use a wider variety of batting strokes to direct the ball in many directions into a field which provides much more open space than in baseball. In addition, cricket batsmen are under no obligation to attempt to score a run after any stroke, but must strike balls in order to prevent them from hitting the wicket. Many strokes are in fact defensive in nature against a well-bowled ball and the quality of defensive batting is often the determining factor of a batsman's success over his career, especially in the longer forms of the game.

By contrast, the balance of power is largely reversed in baseball. While particularly skilled batters have some ability to place hit and direct the ball to desired locations, the pitcher's influence is much more dramatic. Pitchers induce more ground outs, fly outs, or strikeouts, depending on the style of pitch. Thus particular pitchers are known for causing batters to make certain kinds of outs, depending on their mastered pitches. Also in contrast to cricket, baseball batters must attempt to take first base on any ball put into fair territory, and failing to do so will result in an out, but the size of the strike zone more strictly limits the set of deliveries that must be swung at compared to cricket. Like cricket, baseball batters do have a defensive tactic available; many batters will often attempt to deliberately foul off pitches that are strikes yet difficult to hit well, by hitting them into foul territory, awaiting an easier delivery later in the at-bat. Since an uncaught foul ball cannot be a third strike (unless it was a bunt attempt), this tactic allows the batter to receive more pitches.

In the early generations of baseball, the emphasis was mostly on bat control, place hitting, bunting, etc. But, starting in 1919, several factors resulted in a dramatic expansion of strategic orientation, supplementing traditional "small ball" with the "power game": a "livelier" ball, because of better materials and a tighter weave; more frequent substitutions of new balls; lighter, more flexible bats; the outlawing of the spitball; and the increase in attendance which drove owners to build more outfield seating, thus reducing the outfield area significantly. The power game has been encouraged further in recent years, by the construction of new ballparks with smaller outfields than previously, and even the reduction of field size at "classic" ballparks known for spacious outfields; for example, the distance to the fence in deep left field at the original Yankee Stadium was reduced from 430 to 399 feet (131 to 122 m) between 1984 and 1988 (the post-1988 dimensions were maintained at the current Yankee Stadium). Still, it is generally agreed that no one can hit a home run at will, and every successful batter knows never to go to the plate intending to hit a home run. Rather, he should attempt a level swing, try to pull only the ball on the inside of the plate, go the other way with balls low and outside, and otherwise start each at bat intending to drive the ball up the middle, which is the most vulnerable part of the infield (especially if the pitcher is not particularly good at fielding his position).
The games emphasize power hitting to different degrees. Cricket requires the accumulation of large numbers of runs, so placement of the ball between the fielders produces runs efficiently and is generally accepted as a better strategy than "swinging for sixes". In baseball, power hitting can produce runs quickly and frequently in many situations[citation needed], as well as force pitching changes and other fielding moves; but it can also result (because of the great difficulty of driving a ball off a cylindrical bat) in a great many strike outs, fly outs, and ground outs. In cricket situations can arise in a match where power hitting, also called "slogging", is required. This typically occurs towards the final overs of a limited overs game.

Bowling/pitching[edit]

Main articles: pitching (baseball) and bowling (cricket)
Cricket bowlers, since they are not restricted to a small strike zone as their target, also use a wide variety of approaches which are not available to baseball pitchers. These involve varying the line and length of deliveries and using unpredictable movement caused by the ball bouncing on the pitch before it reaches the batsman. Baseball pitchers, by contrast, must use changes in ball speed and movement (cricket bowlers also vary ball speed) caused only by air friction and spin to deceive batters, as most pitches which come near touching the ground are ineffectively allowed to pass as balls. The raised undulating stitching on a baseball allows an accomplished pitcher to create a huge variety of motions in the air; even fastballs are thrown in such a way as to create certain kinds of movement. The cricket ball also moves in the air, to a lesser degree than the baseball, but it achieves its most pronounced movement on the bounce, with seamers landing to ball on the seam to create slight but unpredictable turn, and spinners using spin to create significant turn and bounce variation. Furthermore, pitchers must begin their throw from a stationary position, while bowlers may run up to their delivery. (In the early days of baseball, the pitcher pitched from anywhere within a "box" and so had more flexibility as to where to stand when releasing the ball, before the 1880s.) Baseball pitchers also throw from an elevated mound (10 in or 25 cm above the level of home plate), while cricket bowlers are at the same height as the batsman and must bowl with an overarm (or roundarm, a style rarely seen today) rotation of the arm during which the arm must not straighten by more than 15 degrees. (This was also a restriction on pitchers in the early days of baseball, abolished in the 1880s; today, baseball pitchers use a variety of delivery motions discussed below.) Despite the differences in delivery action, the delivery speeds are similar for both sports with the fastest bowlers and pitchers propelling the ball in the region of 95–100 mph (150–160 km/h): the fastest recorded cricket delivery is 100.2 mph (161.26 km/h)[8][9] with baseball's record quicker at 105 mph (169.0 km/h).[10] It is the case, however, that baseball pitches near or at 100 mph are considerably more common than bowled balls of comparable velocity in cricket. The bowler in cricket is much more restricted with respect to how much he can straighten his arm in delivering the ball, and this is one very significant reason why baseball pitchers can deliver the ball faster with more frequency.
One main difference, however, is that the ball in cricket is harder and heavier in weight. The legal weight for the ball in baseball must weigh between 5 to 5.25 ounces (142 to 149 g). Whereas, the ball in cricket must weigh between 5.5 to 5.8 ounces (156 to 164 g).
Another significant reason for the difference in pace is also the fact that in baseball the ball reaches the batter on the full, whereas in cricket most of the time the ball is bounced off the pitch before reaching the batsman which does take pace off the ball, especially on drier dustier pitches.
Cricket's bowlers are grouped into different categories based on their bowling style—pacemenseamersoff-spinners (or finger-spinners), leg-spinners (or wrist-spinners)—though a bowler may fall into more than one category (pace and seam bowling, for instance, largely overlap). The faster bowlers usually open the bowling, when the ball is at its hardest. Spin bowlers generally bowl later, when the ball has begun to deteriorate and become rough.

The typical motion of a baseball pitcher throwing from a set position.
Baseball's pitchers are classified primarily by their throwing hand (left or right, with left-handed pitchers often called "southpaws") and their usual role in games. A starting pitcher begins games, typically not more than one game in five, in a rotation with four teammates who are also starters who will start games in a sequential cycle, and usually pitch five or more innings. Starters rarely appear as substitutes in games started by others. A relief pitcher enters games later, sometimes on short notice in crisis situations in which there are already runners on base and/or the opponent's best hitters due to bat, and usually pitches fewer innings in any given game. But relievers may be called upon to pitch in several games consecutively. Some relievers even specialize further strictly as closers brought in just to pitch the last inning of a game in which his team leads by a narrow margin. Perhaps the most specialized group of relievers is left-handed specialists—left-handed pitchers who pitch almost exclusively to left-handed batters (sometimes to switch-hitters who are weaker batters right-handed). More often than not, such a pitcher will face only one batter in a given game.
Pitchers are sometimes secondarily grouped according to pitching style, type of pitch most often used, or velocity. This is especially common when pitching technique is rare or unusual. For example, there are many different variations on how the pitch is delivered, including the conventional overhand in which the ball is thrown from the 12 o'clock position, 3/4 styles (with the arm moving towards the plate between 12 and 3 o'clock), as well as the less common sidearm (3 o'clock arm angle, compare roundarm bowling in cricket) and 'submarine' (below 3 o'clock, compare underarm bowling in cricket) deliveries. The submarine pitch is rare, and a pitcher who throws in this way usually has a 'submariner' attached to his name or description. Similarly, there are many kinds of pitches thrown, including the fastball, curve ball, slider, and knuckleball. Capable knuckleballers are extremely rare and are usually described by this skill first.
For reasons that continue to spur debate, it is historically the case that most right-handed pitchers succeed at higher rates against right-handed hitters than against left-handers, and that most left-handed pitchers succeed at higher rates against left-handed hitters than right-handers.
One substantial strategic element to baseball is to utilize this phenomenon as much as possible. Defenses try to force a match between pitcher and hitter by side, and offenses attempt to mismatch them; both teams use substitutions at times to accomplish the desired outcome. One response to this phenomenon is that many hitters, among them a number of the finest and most powerful to play the game, such as Mickey MantleEddie Murray, and Chipper Jones, became adept as youngsters to hitting both left-handed and right-handed to prevent defenses from utilizing that advantage against them. Many professional clubs employ as many as two or three switch hitters so as to neutralize the advantage of side selection. However, only one switch pitcher has played in the major leagues in modern times.

In addition, if a baseball batter is struck with a pitch, he is awarded first base; "hitting" the batter includes hitting loose parts of his uniform without hitting his body (baseball rules specify that a player's person includes his uniform and equipment (but not his bat)). Pitchers may throw close to the batters, and a "brushback" is often used as an intimidation tactic. Deliberately hitting a batter is fairly uncommon, however, chiefly because it is punished severely. If the umpire believes a batter was intentionally hit, the umpire has his discretion on a first offense to warn both benches that the pitcher for either team will be expelled from the game if there are any further hit batsmen (the one baseball term in which "batsman" is used). The warning—and the power to expel if it is contravened—is intended not only to protect batters but to avert fighting; being hit by a fastballis taken seriously by batters, and bench-clearing brawls occasionally result when one team decides the other is deliberately throwing at its batters. Amazingly, in the history of the major league game, only one player has ever been killed by a pitched ball striking him in the head (Ray Chapman of the Cleveland Indians in 1920). This occurred before the invention of the batting helmet and was the principal cause for introducing this piece of equipment into the game as well as replacing dirty balls and outlawing the spitball.
In cricket, bowlers consider the right to hit a batsman as part of their armoury; indeed, one of the most common methods of dismissal (leg before wicket) requires the bowler to hit the batsman's body rather than his bat. A fast bowler will punctuate his overs with deliveries intended to bounceup toward the batsman's head, either to induce a poor shot from self-defence which may result in the batsman being caught out, or to intimidate the batsman, making him less likely to play forward to the next few deliveries for fear of injury. These tactics have long been an accepted part of cricket. In the modern game, batsmen usually wear helmets and heavy padding, so that being struck by the ball only rarely results in significant injury—though it is nevertheless often painful, sometimes causing concussion or fractures (although, it can also have fatal consequences as with the death of Phillip Hughes after having been struck in the head/neck area by a Sean Abbott bouncer during a Sheffield Shield match in 2014). Baseball batters wear helmets, but they are unsecured and lack the "cage" since only one side of the head/face is exposed. Catchers typically wear a helmet with a cage or protective bars. An equivalent ball to striking the batter in baseball would be a beamer, where the ball hits the batter's upper body area without bouncing first. These are rare and usually caused by the ball slipping out of the top of the bowler's hand. The even rarer intentional beamer provokes strong reaction from batter and crowd alike. The umpire is authorized to take disciplinary action in such instances. The bowler is generally given a first warning, and is dismissed from the game if the offence is repeated. A notable case of this happening was between Waqar Younis and Andrew Symonds in which Younis was banned from bowling by umpire David Shepherd for delivering a beamer to Symonds during the match between Pakistan and Australia at the 2003 World Cup as it had never happened during an international match prior to then.
There is a major difference in the way in which different bowlers or pitchers contribute to a single game. In baseball, a single pitcher starts the game, and makes every pitch until a point where the manager replaces the tiring pitcher with a relief pitcher. Replaced pitchers cannot return to pitch again in the same game (unless they are shuttled to another position in the field and thus stay in the lineup, a move rarely done in the major leagues), and a succession of pitchers may come into the game in sequence until it ends. In cricket, multiple bowlers begin the game, with those not actively bowling spending time as fielders as every player in the team including the wicket-keeper but excluding the 12th man is available to be used as a bowler. Bowlers alternate bowlingovers of six balls each, moving to fielding positions to rest before returning to bowl again later in the game. A bowler will usually bowl for a 'spell' of several (alternate) overs, and will generally bowl the entire spell from the same end of the pitch. A second bowler will bowl the overs missed by the first, from the other end of the pitch, for his own spell. Although moving a pitcher to a fielding position and returning him to pitch later in the game is legal in baseball, it is a rarely used and potentially risky strategy, as the pitcher may be unprepared to play another position.
The terms "bowling" and "pitching", as words, both denote underarm deliveries, as were once required in both games. The rules for delivery were also initially very similar. Once overhand deliveries were permitted in the respective sports, and pitchers were compelled to toe the pitching rubber instead of throwing from anywhere within the "pitcher's box", the actions of bowling and pitching diverged significantly.
The "wide" in cricket and the "ball" in baseball both derive from the concept of a "fair" delivery, i.e. a delivery that the batter or batsman has a fair chance of making contact with his bat. While there is no sharply defined "strike zone" in cricket as there is in baseball, in both cases the umpire must judge whether the ball was delivered fairly. Both the "wide" and the "ball" result in a "penalty". In cricket, like a no-ball a single run is charged and it does not count as a legal delivery. In baseball, a ball is called, and if a pitcher gives up four balls the batter is awarded first base, which is called a "base on balls" or a "walk". A walk will only score a run directly if the bases are already loaded, forcing the runner at third base to advance to home (known as "walking in a run"); otherwise the threat is merely of another runner reaching base instead of making an out. However since runs are scored so much more frequently in cricket, a wide scores a run directly shouldn't be taken too seriously, although the extra delivery can be of vital significance toward the end of a match. In both games, a wide or a ball can be the decisive factor in winning a match or a game.

Running[edit]

Running plays a much larger role in baseball because of the low scoring and also, they must run much further to score a run, because runners may remain in play (that is, on the bases) without scoring, and because baserunners can advance to the next base before the ball is hit again (steal the base) as soon as the ball is live. Base stealing often requires sliding, in which the runner throws himself to the ground to avoid both being tagged or overrunning the base. The runner may also deliberately slide into the fielder at the base he is trying to steal to keep him from catching the ball or to disrupt a double play. At home plate the runner often will simply, and legally, run into a catcher who is blocking the baseline but who does not have the ball (a defensive player may not impede the runner unless he has the ball or is in the process of catching it).
The equivalent in cricket is almost impossible because the bowler is next to the runner, and in fact used to be able to mankad him if he strayed out of his crease; nowadays the batsman can leave the crease when the bowler's back foot touches the ground during his delivery action without risk of being 'Mankaded'. Tactical running in cricket rarely strays beyond the consideration of "can I make it to the other end before the ball does". One exception of this is towards the end of a closely fought limited overs game, where a batsman (normally a tail-ender) would sacrifice his wicket in order to allow the better batsman to remain on strike, usually in the last few balls. While in baseball, steals, sacrificial running, forces, double plays, intimidation, and physical contact enter into the equation.
Making contact with a fielder, as baserunners often do, would be unsportsmanlike in cricket, and unnecessary, as play stops when a single wicket is taken. Occasionally a cricket runner will dive over the crease, but in baseball this is a regular occurrence, as players are frequently forced to run even when their chances are slim.
Since a team almost always scores fewer runs in a baseball game than its number of outs, a baserunner will frequently take risks attempting to advance an extra base or score run, resulting in close plays at a base. In cricket, since the number of runs scored is much greater than the number of wickets taken in a match, a batsman would be very foolish to risk getting run out in an attempt to score an extra run without a very high expected chance of success. In general, cricket batsmen are run out due to exceptional fielding, poor judgment/communication, or a combination of the two. In baseball, runners are often out not of their own accord - they are simply forced out.

Game length[edit]

A direct comparison is difficult since cricket is predominantly played in three different formats: TestOne Day and Twenty20. Of these, the Twenty20 format is similar in terms of the amount of time it takes to play a game of baseball, around three to three-and-a-half hours. Baseball games are generally much shorter than Test and One Day cricket games. Most Major League Baseball games last between two-and-a-half and four-and-a-half hours. Because the Major League playing season is 6 months long (183 days, between April and October with Spring Training in February and March), with 81 games played at home and 81 away (162 in all, not counting the postseason or the All-Star Game), baseball teams often find themselves playing double-headers and series games. A doubleheader entails two games, played back to back, in one day. This usually occurs when a game needed to be rescheduled, and is a common occurrence during the beginning of the Major League season, which coincides with the rainy Spring season. Although they were once common, double-headers are rarely scheduled anymore by teams, but are part of the culture of baseball, with Ernie Banks' "Let's play two" a famous refrain. A series occurs when two teams play on several consecutive days. This is a part of the regular schedule in baseball because of the number of games required in a season, and because there are large distances between stadiums in the U.S. and Canada, thus conserving time and resources by allowing the teams to spend several days in a single location. In Major League Baseball there is a maximum of 20 days consecutively played before a break in games must be observed.
Test Cricket games can last up to five days with scheduled breaks each day for lunch and tea, giving three sessions of play each day. The one-day games version of the sport usually lasts from five to seven hours, but can sometimes continue for longer than eight hours. Twenty20 has innings of twenty overs per team. The average time it takes to play an individual game of Twenty20 cricket is similar to the amount of time it takes to play a game of baseball, around three to three-and-a-half hours.
ODI and Twenty20 cricket, with their inherent limit on the number of fair deliveries, do not have an exact equivalent in baseball. The closest comparison would be games that have a pre-set number of innings shorter than the standard 9 (as with the second game of a doubleheader at some levels) or a pre-set time limit of some kind, such as a curfew restriction, or in the case of one of baseball's cousins, recreational softball, a pre-set length of the game, such as one hour.

Strategy[edit]

A wide array of factors affect both games (from composition of the pitch or field soil to weather conditions, wind, and moisture) and numerous strategies in both games can be employed to exploit these factors. Other than the bowler, cricket places very few restrictions on fielding placement, even for the wicket-keeper, and its variety of bowling styles, 360 degrees of open field, wide bowling area (target zone), and so on provide for strategic play. Notable exceptions include the limit of two fielders in the leg side quadrant, introduced to prevent the use of Bodyline tactics, and limiting outfield players in the early stages of one-day cricket matches and the subsequent introduction of powerplays. In baseball, has very specific rules about the positions of the pitcher and the catcher at the start of each play. The positioning of the other seven fielders is as flexible as cricket, except that each one must start the play positioned in fair territory. The fielders are otherwise free to position themselves anywhere on the playing field, at their discretion based on the game situation.

Condition of the ball[edit]

A major element of strategy in these sports is the condition of the ball. Since bowling in cricket has more variations (such as bounce, swing, seam movement, off-spin, leg-spin and so on), the condition of the ball also affects play to a great degree. In Test cricket, the same ball must be used for at least 80 overs unless it is lost, damaged or illegally modified and then it must be replaced with a ball of a similar condition, after which, obtaining a new ball is at the discretion of the fielding captain whereas, in baseball the ball is replaced numerous times during a game to ensure it is in optimum condition. Often, the fielding captain might opt for the new ball straightaway, since a new ball is harder, bounces higher and has an intact seam, which produces greater conventional swing. But when a captain feels that a spin bowling attack is more likely to be successful, he will persist with the old ball, which is rougher and better grips the surface as well the bowler's fingers.
The aerodynamics of swing in cricket are different from baseball. Moreover, the raised seam also causes movement off the pitch in cricket, which is a very important part of medium pace bowling. Once a particular hemisphere of the cricket ball is more rough or scratched than the other, the fielding team meticulously works to preserve the shine on the other half by rubbing it on their clothes or by applying saliva (no "external" substances can be applied to alter the condition of the ball). Bowlers very carefully regulate their wrist position at the point of release to ensure the shine is preserved only on one half of the ball, since it will swing towards the rough side.
The old ball in cricket also tends to generate greater amounts of reverse swing, which is swing towards the polished side. This can be exploited by a captain with genuinely fast bowlers (usually, those who can bowl over 90 mph or 140 km/h) at his disposal. Especially on pitches in the Indian sub-continent, which tend to have abrasive surfaces, bowlers might resort to bowling across the seam as early as the tenth over, so as to quickly scruff up the ball and generate reverse swing early on. Strategies that rely on early reverse swing also need the backup of effective spin bowlers to be able to exploit the roughed up ball.
Due to these factors, a batsman in cricket needs to very carefully watch how the bowler grips the ball even during his run-up, as well as the type of revolutions on the ball as it approaches. Master spin bowlers like Shane Warne & Muttiah Muralitharan, who were able to dramatically vary the trajectory, direction and extent of spin, regularly bowled deliveries with a scrambled seam to disguise the type of ball actually bowled.

Batting first or last[edit]

In cricket, since the strategies are greatly influenced by factors such as soil characteristics of the pitch, condition of the ball, time of the day, weather and atmospheric conditions, the decision to bat first or last is of great tactical importance.
The team that wins the coin toss has the choice of batting first or last. Selection of batting first or last can be crucial to success; particularly in Test cricket. As the pitch is used for up to five consecutive days with little maintenance, the deterioration of the pitch with wear can have a major influence on the result of the match (e.g. Typically the ability of spin bowlers to ‘turn’ the ball increases toward the end of a Test match, whereas fast bowlers often prefer a harder and bouncier pitch often found at the start of a test match). It is usual for some amount of grass to be left on the pitch on the first day of a Test, since it helps bind the surface. The presence of grass on the pitch is conducive for pace bowling, so a grassy pitch may also tempt a captain to bowl first. Sometimes, current weather conditions also influence the decision, since a cloud cover has empirically been known to assist swing bowling. Aggressive captains such as Allan Border of Australia have been known to bat first in Test cricket regardless of the conditions.
In One Day International cricket, the time of day is also a crucial factor in determining the captain's decision at the toss. In some parts of the world, dew on the ground can be significant. For a day-night game, grounds in some countries like India or South Africa become wet due to dew, which makes it difficult for a spinner to grip the ball. The captain must balance this against a consideration for bowling becoming more effective under lights, since the ball might skid off any dew on the pitch or get assistance in swing from the cooler night-time air. Even for a day game, the captain might be inclined to exploit early morning dew on the pitch.
In baseball, on the other hand, the "home" team always bats last. This was not originally the case. In the early years, the winner of a coin toss could decide whether to bat first or last. The more offense-oriented aspect of the early game might influence a team's decision to bat first and hope to get a quick lead. This led to the occasional unfortunate situation where the home town crowd would have to watch their team lose a game in the last of the ninth inning, in "sudden victory" fashion by the visiting team. By the late 1800s, the rule was changed to compel the home team to bat last. At a "neutral" site, such as the College World Series, the "home" team may be decided by coin toss, but that "home" team must bat last.

Fielding strategy[edit]

The normal fielding arrangement in baseball.
In cricket, since the batsmen can hit the ball with greater variation and different objectives, the field placements are more important and varied. Modern-day coaches and captains have intricate knowledge of the strengths of opposition batsmen, so they try to plug the dominant scoring areas for each batsman. Moreover, since the bowling attack has greater variety in cricket, the field placements required for each type and line of attack also vary greatly.
Depending on the scoring strengths of the batsman (off-side, leg-side, straight, square, front foot, back foot, power hitter, "finds the gap", "clears the field" and so on), the captain must make adjustments to the field each time the batting pair score a run and change ends, which can possibly happen after every ball in an over. To meet the demands of a speedy over-rate (typically, about 15 overs an hour), the captain must arrange the fielders in a way that they can swiftly interchange positions for the two batsmen. This is especially important if one batsman is right-handed, while the other is left-handed. And also in one- day cricket if the umpires deem the over rate of the team fielding first is too slow they can dock them overs so they may have less than 50 overs to reach their target score when it is their turn to bat.
Fielders in cricket can field in all positions, but modern players have specialized field positions. In particular, slip positions require special skills since the slip fielder is placed behind the batsman and the ball comes directly off the edge of the bat. Close catching positions such as forward short leg and silly point, as well as positions for the cut shot such as gully and point, require very fast reflexes and canny anticipation, so they are also specialist positions.
Cricket strategy requires creative use of the many possible fielding positions.
In baseball, although only the positions of pitcher and catcher are prescribed by the rules, fielders' positions are dictated closely by custom, and shifts in fielders' positions according to circumstance are less dramatic; the strike zone and smaller angle of fair territory limit the usefulness of some strategies which cricket makes available to batsmen. The chief occasion on which fielding placement differs markedly from the usual is the presence of a pull, or dead-pull, hitter at bat (such hitters almost never, except on the rare occasion of a fluke or mishit, hit the ball in any direction except towards the same side of the field as they stand at the plate, i.e. a right-handed pull hitter hits everything toward left field). In such case the fielders will move so far in the direction of the pull that one half of the field is almost completely unprotected. This is called an overshift. A six-man infield has also been used when circumstances warrant. For the great majority of batters, however, the traditional fielding arrangement is used, with minor changes in position to accommodate the batter's power or bat-handling ability, the location of runners, or the number of outs. (For example, with a base runner on third with less than two out, the importance of fielders being able to throw quickly to home plate on a bunt is increased, and the infielders will play closer to home plate.) However, Baseball has no equivalent of Cricket's close-in fielders, because it is impractical to have fielders so close to the bat as they would have virtually no chance of latching onto a ball travelling so fast. It is possible to place a close-in fielder to catch a bunt, but this practice is almost never followed in real life except in specialized circumstances such as a pitcher being forced to bat late in a game, with less than two outs and the opportunity to drive in a run. The team's best chance to score in such a situation may be tosacrifice bunt and may warrant the first or third baseman playing halfway up the line to cut off the run at home.
In cricket, coaches cannot intervene or direct gameplay; the captain must make all the calls once the players are out on the field. However, the coach may convey messages to the captain or the players at any time, since there is no restriction on signaling or speaking to players on the field. In dynamic situations, like a run chase with an imminent possibility of rain, it is quite common for coaches to update tactics using signals. Hansie Cronje, the former cricket captain of South Africa, once took the field with a wireless link to the coach, Bob Woolmer. Subsequently, the use of gadgets to transmit messages was banned by the International Cricket Council. Regardless, the coach is merely an adviser, it is almost always the case that the cricket captain has complete authority over the team once play starts. In baseball, by contrast, managers and coaches will often direct the players (through hand signals) to carry out a play (such as a stolen base or hit and run), or to field at a particular depth. In fact, "stealing signs" can play an important part in baseball strategy when a player on an opposing team tries to interpret hand signals between pitcher and catcher or between runner and base coach, and possibly then relay this information to another player without being themselves detected.

Strategy over the course of the game[edit]

Pickoff attempt on runner (in red) at first base
In both sports, strategy varies with the game situation. In baseball, pitcher, batter and fielders all play far differently in the late innings of a close game (e.g., waiting for walks, trying for stolen bases or the squeeze play to score a decisive run) than they do early, or when one team has already scored many more runs than the other (where batters will be likely to swing at many more pitches and try for extra-base hits and even home runs). The number, speed, and position of baserunners, which have no equivalent in cricket, all dramatically change the strategies used by pitcher and batter. A runner on first base must decide how large a lead to take off the base—the larger the lead, the greater the chance of advancing on a stolen base or batted ball, but also the greater the risk of being picked off by the pitcher. In leagues which do not allow designated hitters, strategic thinking also enters into substitutions. For example, in the double switch, the substitution of a relief pitcher is combined with the substitution of a pinch hitter who takes the pitcher's spot in the batting order so that the new pitcher will come to bat later (as almost all pitchers are poor hitters). Since players may not return to the game after being substituted for, a manager cannot take lightly the decision when and if to substitute a better-fielding but worse-hitting player if his team is ahead.
Another difference between baseball and cricket strategy is the importance of sacrifice plays in baseball. These are plays in which a batter deliberately hits in a particular way or in a particular direction in order to advance runner at the expense of himself getting out. For example, a poor batter may deliberately bunt (hit a low slow ball) a ball towards first base so that he will be easily put out, in order to ensure that a runner on second base will end up safe on third. A stronger batter may deliberately hit a long "sacrifice fly" that he knows will be caught (resulting in an out) so that a runner can make it home to score a run. This strategy results from the relative cheapness of individual outs in baseball and the relative importance of individual runs in that sport compared to cricket, where such a strategy would be foolish as runs cannot be scored when wicket has fallen except in the case of either a run-out or a stumping.
The essential action in baseball is either (for the offense) to advance runners around the bases or (for the defense) to halt that advance. As simple as this is in principle, in practice it generates a remarkably large range of strategies. Any given situation—the number of runners on base, the bases they occupy, their skills as runners or base-stealers, the count on the hitter, the number of outs, the specialties of the pitcher and the batter, the catcher's skill at throwing out runners, the positioning of fielders, which inning is being played, and so on—allows for a considerable variety of possible plays, on either side of the ball. At any moment, one manager may be calculating how to advance his runners (whether to call for the steal, the hit-and-run, sacrifice bunt, sacrifice fly, a double steal, the squeeze, and so on) while the opposing manager is calculating how best to thwart his opponent (not only through the pitching approach and positioning of fielders, but by, say, calling for a pitch-out when a steal is anticipated, and so on). Since the variables that determine which strategies are possible or advisable change from pitch to pitch, and according to all the varieties of play situation that may come about in any game, the game played between the two managers is the most intricate aspect of the game, and for many followers of the sport[who?] is considered the true 'inner game'.
First-class cricket also has a number of strategic elements not found in baseball, simply because the maximum time duration of the game is fixed (which can be up to five days for Test cricket) and a match not completed by the end of the time duration results in a draw regardless of the relative score. By contrast, baseball games are played to completion regardless of the time duration and there is no possibility for a tie or draw (with the exception of certain exhibition games such as the MLB All-Star Game, or in the case of Japan, where games are declared ties after 12 innings[11][12]). There are no equivalents in baseball of, for example, deciding when to declare or whether or not to make your opponent follow on.

Strategy based on the playing surface[edit]

The condition of the playing strip (the pitch) in cricket is of vital significance as, unlike baseball, the ball is deliberately bounced on the pitch before reaching the batsman. While in baseball, playing conditions between different stadia are much the same (except for perhaps small differences in the dimensions of the field, whether the outfield is fast or slow, and if the field is grass or artificial turf), the physical characteristics of the cricket pitch can vary over the course of the game, or from one field to another, or from one country to another. On the Indian subcontinent, for instance, pitches tend to be dry, dusty and soft. These pitches offer less assistance to fast bowlers because the ball tends to bounce slower and lower, where most fast bowlers rely on bounce and speed to defeat the batsman. On the other hand, spin bowlers prefer this surface because it gives greater traction to the ball and will result in the ball breaking or turning more when it hits the surface. When such a delivery is bowled, the ball is said to have "turned". Conversely, pitches in places such as Australia, England, South Africa or the West Indies tend to be hard, true surfaces, called "batting wickets" or "roads" because the ball bounces uniformly and thus batsman find it easier to score runs, although these wickets suit fast bowlers more than spinners. Accordingly, teams are generally much harder to beat in their own country, where both their batsmen and bowlers are presumably suited to the types of pitches encountered there. On any given pitch, however, conditions will become more suitable for spinners as time progresses as the pitch becomes softer and worn through use, making the spin bowler something of a cricketing "closer". The pitch can be cleaned of debris and rolled between innings, and should be mowed before each day's play at the discretion of the umpires. But the pitch cannot be watered once the match has started.[13] Its characteristics can therefore change during the game, and can be a major factor in deciding whether to bat or field first.
Baseball parks are also not completely uniform, however many of the variations in playing conditions in baseball also arise in cricket. Stadiums with retractable roofs, for example, usually play differently with and without the roof. For example, with the roof open the wind will affect how far the ball carries. Against a running team the basepaths may be heavily watered. Many stadiums have idiosyncratic features – for example, the short right field and high left field wall (called the Green Monster) at Fenway Park, the hill and flagpole in the outfield (Tal's Hill) at Minute Maid Park, or numerous "porches" (parts of the grandstands hanging over the outfield, such as the "Short Porch in Right" at Yankee Stadium) which allow short home runs. There is an equivalent for this in cricket, where the placement of the pitch may render one perpendicular boundary significantly shorter than the other. For example, at a particular ground, the leg-side boundary may be 15 feet closer to the batsman than the off-side boundary. Such a boundary can then be targeted by batmen in search of quick runs.
The baseball behaves differently in those stadiums with artificial turf as well. Artificial surfaces are harder and more uniform than grass, and the ball tends to roll farther and straighter, and to bounce truer and more highly on these fields. Teams built to play the majority of their games on this field tend to place a higher premium on defense (since it is more likely to get an infield out) and speed (since it is more important to be able to beat out a throw) than on power hitting.[14]
The altitude of the stadium (most notably Coors Field) can also impact the distance a batted ball travels and the amount of ball movement a pitcher can generate with his deliveries, although recently balls have begun being placed in humidors at high-altitude parks to negate these effects. The amount of moisture in the dirt on the basepaths can also affect the behavior of ground balls and the ease with which players may steal bases; some teams are known to alter the amount of watering done to the dirt depending on the skills of the home and visiting team. The amount of foul territory is also an important variable, since foul pop-ups that would be outs in some parks (e.g. the Oakland Coliseum) may end up in the stands in other parks, thereby allowing the batter to remain at the plate (e.g. Fenway Park and Coors Field). On the whole, though, these variations do not produce effects as great as variations in cricket pitches, with one arguable exception being Coors Field.
In general, the condition of the pitch is a much greater factor in cricket than in baseball, while at the professional level stadium shape and quirks permanently built into the playing surface are greater factors in baseball than in cricket. Note that in amateur cricket pitches may have considerable variation in shape and may even incorporate obstacles (like trees), but this is not considered desirable or ideal. In baseball, familiarity with distinct field layout is considered to be an important part of having home-field advantage.

Strategy based on batting order[edit]

The batting order in baseball must be declared before the game begins, and can only be changed if a substitution occurs. Batting out of turn is a rule violation resulting in a penalty. When a manager makes a substitution, the new player must occupy the same place in the batting order as the old one. To allow more complicated changes in batting order, managers may use the double switch, substituting for two players simultaneously. This is typically used to replace the pitcher but put the new pitcher in a spot in the batting order that will not come up to bat soon, previously occupied by another fielder (pitchers are almost uniformly poor hitters much like most frontline bowlers are poor batsmen). However, the rule remains that no individual player can ever change his position in the batting order within the same game.
Unlike baseball, the batting order in cricket is not fixed, and can be changed at any time, provided each player bats at most once. This gives rise to the "pinch hitter" in cricket - a non-specialist batsman promoted up the order to get quick runs -, and the Nightwatchman. This latter is typically a non-batsman promoted up the order at the end of the day to avoid a better batsman having to make two cold starts, a particular risk. If a batsman is not ready to bat at the fall of a wicket, another batsman- typically the player who occupies the next spot in the batting order will go out to bat in his place in order to eliminate the risk of him being timed out.
The roles of individual players in the batting order are strikingly similar. In both sports, the players near the top of the batting order are considered superior batters or batsmen. The initial batters or batsmen generally specialize in avoiding making outs, while the third through fifth batters and batsmen are considered their team's best at providing runs. After that, the talent generally drops off, with the pitchers and bowlers generally being the worst at batting. Because outs are less important in baseball than in cricket, poorer batters are sometimes asked to attempt a "sacrifice" play in which they deliberately get themselves out in baseball to achieve a bigger team goal. This only occasionally happens in cricket, at the end of a limited-overs game, where a poorer batsman may sacrifice himself so that his partner will be on-strike for the next delivery. Also, since in baseball a batter who puts the ball in play does not get another at-bat until the entire batting order is cycled through, the opposing team may pitch around a skilled batter, deliberately walking him so that another batter comes to the plate. In cricket, a batsman remains at the pitch until he is out (or the team is all out or, his captain declares or, the set number of overs have been bowled), and the other team must bowl to him until he is out. The only way captains can negate the influence of superior batters similar to pitching around is to try and keep the more skilled batsman off-strike. This can be seen at the end of closely fought matches, where a captain might try and maximize the number of deliveries his bowlers can bowl at a non-specialist batsman. The exception is if the player is injured and has to leave the field for treatment, the next batsman in the order will take his place. If the original batsman is able to continue later on, he can join the game again when one of his teams batsmen is out provided his injury time has expired or after 5 wickets have fallen, whichever comes first provided the rest of the team isn't bowled out before either of these situations arise.

Equipment[edit]

Professional baseball bats are typically made of ash or maple; hickory used to be popular, as well.
Baseball players use thin, round bats and wear gloves to field (with the catcher wearing a special, more protective glove), while cricketers use wide, flat bats and field barehanded (except for the wicket-keeper, who wears gloves and protective leg pads). Note that while baseball fielders' gloves do provide modest protection against impact, they are used primarily to extend reach and are generally not padded (except for the catcher's glove). In cricket a batsman wears protective gear such as pads, gloves, thigh pads, helmet, a chest guard, an arm pad and a box (which is used to protect the groin area), whereas the only required protective gear for baseball batters is an unsecured helmet (as required in major league baseball rule 1.16); many batters also use elbow, shin, ankle, or hand protectors, and most wear a cup (a groin protector) and use batting gloves (similar to golf gloves) to aid grip.
Another difference between the two sports involves the condition of the ball as a match progresses. In cricket, if a ball is hit into the stands, the spectators must return it to the field. Also, a ball that is scuffed or scratched will continue in use; a ball must be used for a minimum number of overs (currently 80 in Test cricket and 25 in One-Day-International cricket with a different ball being used from each end) before it can be replaced. If a ball is damaged, lost, or illegally modified, it is replaced by a used ball of similar condition to the old one. Finally, cricketers are allowed sparingly to modify the ball, though this is highly restricted. The ball may be polished (usually on a player's uniform) without the use of an artificial substance, may be dried with a towel if it is wet, and may have mud removed from it under supervision; all other actions which alter the condition of the ball are illegal. In Major League Baseball (MLB), a ball that is hit into the stands is never returned to play and spectators are free to keep any balls that come into their possession (although local tradition may provide for a ball to be thrown back, specifically in the case of home-run balls hit against the Chicago Cubs when playing at Wrigley Field).
Moreover, baseballs are replaced on a regular interval during the course of a game. Major League Baseball requires the home team to supply the baseballs that will be used during that day's games. MLB further require that the home team make available at least 90 new baseballs to theumpires prior to the start of the game. Generally, a baseball is replaced every time it either is hit by a batter or touches the ground. In a typical Major League Baseball game, baseballs are replaced every five pitches or so with a total game average of around 70 baseballs being used.
Because baseball hitting is difficult, baseball rules prohibit the deliberate scratching or scuffing of a ball, or the application of any foreign substance that could conceivably affect the flight or visibility of a ball. Balls that are deliberately made more difficult to hit by applying foreign substances are often known as spitballs, regardless of the specific substance applied (such as Vaseline). Both spitballs and those that become scuffed or scratched through normal game play are immediately removed from play and never reused. The current rules regarding the condition of baseballs did not come into effect until 1920, after the death of Ray Chapman from being hit with a Carl Mays spitball. Before that point, the rules were similar to those still present in cricket. However, the new rules were not consistently enforced for several decades afterwards, and several pitchers (most notably Gaylord Perry) built careers around skirting these rules, doing such things as hiding nail files in their gloves or putting Vaseline on the underside of their hats. In modern baseball, however, the prohibition against modifying the baseball in almost any way is strictly enforced and players found to be in violation of this rule are not only ejected from the game in which the infraction occurred, but are also subject to a suspension. The only substance applied to a baseball is the Delaware River mud formulathat umpires rub in before a game to remove the "shine" from the ball and improve its grip. The pitcher is also allowed to use rosin on his hands (via a rosin bag) to improve his grip, and to blow on his hands in cold weather.
