In cricket, the rules of the game are codified in
The Laws of Cricket (hereinafter called "the Laws"), which has a global remit. There are 42 Laws (always written with a capital "L"). The earliest known version of the code was drafted in 1744, and since 1788, it has been owned and maintained by its custodian, the
Marylebone Cricket Club (MCC) in
London.
Playing area Cricket is a
bat-and-ball game played on a
cricket field (see image of cricket pitch and creases) between two teams of eleven players each. The field is usually circular or oval in shape, and the edge of the playing area is marked by a
boundary, which may be a fence, part of the stands, a rope, a painted line, or a combination of these; the boundary must if possible be marked along its entire length. In the approximate centre of the field is a rectangular
pitch (see image, below) on which a wooden target called a
wicket is sited at each end; the wickets are placed apart. The pitch is a flat surface wide, with very short grass that tends to be worn away as the game progresses (cricket can also be played on artificial surfaces, notably matting). Each wicket is made of three wooden
stumps topped by two
bails. As illustrated, the pitch is marked at each end with four white painted lines: a
bowling crease, a
popping crease and two
return creases. The three stumps are aligned centrally on the bowling crease, which is eight feet eight inches long. The popping crease is drawn four feet in front of the bowling crease and parallel to it; although it is drawn as a line (six feet on either side of the wicket), it is, in fact, unlimited in length. The return creases are drawn at right angles to the popping crease so that they intersect the ends of the bowling crease; each return crease is drawn as an line, so that it extends four feet behind the bowling crease, but is also, in fact, unlimited in length.
Match structure Before a match begins, the team
captains (who are also players)
toss a coin to decide which team will
bat first and so take the first
innings. In each innings, one team bats, attempting to
score runs, while the other team
bowls and
fields the
ball, attempting to restrict the scoring and
dismiss the batters. When the first innings ends, the teams change roles; there can be two to four innings depending upon the type of match. A match with four scheduled innings is played over three to five days; a match with two scheduled innings is usually completed in a single day.
Clothing and equipment "taking guard" in 1883. His pads and bat are very similar to those used today. The gloves have evolved somewhat. Many modern players use more defensive equipment than were available to Grace, most notably helmets and arm guards. The
wicket-keeper (a specialised fielder behind the batter) and the batters wear protective gear because of the hardness of the ball, which can be delivered at speeds of more than and presents a major health and safety concern. Protective clothing includes
pads (designed to protect the knees and shins),
batting gloves or
wicket-keeper's gloves for the hands, a
safety helmet for the head, and a
box for male players inside the trousers (to protect the
crotch area). Some batters wear additional padding inside their shirts and trousers such as thigh pads, arm pads, rib protectors and shoulder pads. The only fielders allowed to wear protective gear are those in positions very close to the batter (i.e., if they are alongside or in front of him), but they cannot wear gloves or external leg guards.
Bat and ball The essence of the sport is that a
bowler delivers (i.e., bowls) the
ball from their end of the
pitch towards the
batter who, armed with a
bat, is "on strike" at the other end (see next sub-section:
Basic gameplay). The
bat is made of wood, usually
Salix alba (white willow), and has the shape of a blade topped by a cylindrical handle. The blade must not be more than wide and the total length of the bat not more than . There is no standard for the weight, which is usually between 2 lb 7 oz and 3 lb (1.1 and 1.4 kg). The
ball is a hard leather-seamed
spheroid, with a circumference of . The ball has a "seam": six rows of stitches attaching the leather shell of the ball to the string and cork interior. The seam on a new ball is prominent and helps the bowler propel it in a less predictable manner. During matches, the quality of the ball deteriorates to a point where it is no longer usable; during the course of this deterioration, its behaviour in flight will change and can influence the outcome of the match. Players will, therefore, attempt to modify the ball's behaviour by modifying its physical properties. Polishing the ball and wetting it with sweat or saliva was legal, even when the polishing was deliberately done on one side only to increase the ball's
swing through the air. The use of saliva has since been made illegal due to the
COVID-19 pandemic. The acts of rubbing other substances into the ball, scratching the surface or picking at the seams constitute illegal
ball tampering.
Player roles Basic gameplay: bowler to batter During normal play, thirteen players and two
umpires are on the field. Two of the players are
batters and the rest are all eleven members of the
fielding team. The other nine players in the batting team are off the field in the
pavilion. The image with overlay below shows what is happening when a ball is being bowled and which of the personnel are on or close to the
pitch. In the photo, the two batters (3 and 8, wearing yellow) have taken position at each end of the pitch (6). Three members of the fielding team (4, 10 and 11, wearing dark blue) are in shot. One of the two umpires (1, wearing white hat) is stationed behind the
wicket (2) at the
bowler's (4) end of the pitch. The bowler (4) is
bowling the
ball (5) from his end of the pitch to the batter (8) at the other end who is called the "striker". The other batter (3) at the bowling end is called the "non-striker". The
wicket-keeper (10), who is a specialist, is positioned behind the striker's wicket (9), and behind him stands one of the fielders in a position called "
first slip" (11). While the bowler and the first slip are wearing conventional kit only, the two batters and the wicket-keeper are wearing protective gear, including safety helmets, padded gloves and leg guards (pads). The wicket-keeper is the only fielding player able to wear protective gloves. While the umpire (1) in shot stands at the bowler's end of the pitch, his colleague stands in the outfield, usually in or near the fielding position called "
square leg", so that he is in line with the
popping crease (7) at the striker's end of the pitch. The bowling crease (not numbered) is the one on which the wicket is located between the return creases (12). The bowler (4) intends to hit the wicket (9) with the ball (5) or at least prevent the striker (8) from scoring
runs. The striker (8) intends, by using his bat, to defend his wicket and, if possible, hit the ball away from the pitch in order to score runs. Some players are skilled in both batting and bowling, so are termed
all-rounders. Bowlers are classified according to their style and speed, generally as
fast bowlers,
seam bowlers or
spinners. Batters are classified according to whether they are right-handed or left-handed, with
switch-hitting uncommon and largely utilised as a tactic, where a batter changes stance shortly before the bowler releases the ball.
Overs The Laws state that, throughout an innings, "the ball shall be bowled from each end alternately in overs of 6 balls". The name "over" came about because the umpire calls "Over!" when six legal balls (deliveries) have been bowled. At this point, another bowler is deployed at the other end, and the fielding side changes ends while the batters do not. A bowler cannot bowl two successive overs, although a bowler can (and usually does) bowl alternate overs, from the same end, for several overs which are termed a "spell"; if the captain wants a bowler to "change ends", another bowler must temporarily fill in so that the change is not immediate. The batters do not change ends at the end of the over, and so the one who was non-striker is now the striker and vice versa. The umpires also change positions so that the one who was at "
square leg" now stands behind the wicket at the nonstriker's end and vice versa. If a fielder is injured or becomes ill during a match, a
substitute is allowed to field instead of the aforementioned fielder, but the substitute cannot bowl or act as a captain, except in the case of concussion substitutes in international cricket. The
Laws of Cricket were updated in 2017 to allow substitutes to act as wicket-keepers.
Batting and scoring batter is a
mirror image of this one. Batters take turns to bat via a
batting order which is decided beforehand by the team captain and presented to the umpires, though the order remains flexible when the captain officially nominates the team. A skilled batter can use a wide array of "shots" or "strokes" in both defensive and attacking mode. The idea is to hit the ball to the best effect with the flat surface of the bat's blade. If the ball touches the side of the bat, it is called an "
edge". The batter does not have to play a shot and can allow the ball to go through to the
wicket-keeper. Equally, the batter does not have to attempt a run when hitting the ball with their bat. Batters do not always seek to hit the ball as hard as possible, and a good player can score runs by simply making a deft stroke with a turn of the wrists, or by simply "blocking" the ball but directing it away from fielders so that the player has time to take a run. A wide variety of shots are played, the batter's repertoire including strokes named according to the style of swing and the direction aimed: e.g., "
cut", "drive", "hook", and "pull". is the only player to have scored one hundred international
centuries. The batter on strike (i.e., the "striker") must prevent the ball from hitting the wicket and try to score
runs by hitting the ball with their bat so that the batter and their partner have time to switch places, with each of them running from one end of the pitch to the other before the fielding side can return the ball and attempt a
run out (throwing the ball at one of the wickets before the run is scored.) To register a run, both runners must touch the
ground behind the popping crease with either their bats or their bodies (the batters carry their bats as they run) before a fielder can throw the ball at the nearby wicket. Each completed run increments the score of both the team and the striker. The decision to attempt a run is ideally made by the batter who has the better view of the ball's progress, and this is communicated by calling, usually "yes", "no" or "wait". More than one run can be scored from a single hit. Hits worth one to three runs are common, but the size of the field is such that it is usually difficult to run four or more. Hits for five are unusual and generally rely on the help of "overthrows" by a fielder returning the ball. If an odd number of runs is scored by the striker, the two batters have changed ends, and the one who was non-striker is now the striker. Only the striker can score individual runs, but all runs are added to the team's total.
wide, a penalty of one extra conceded by the bowler if they bowl so that the ball is out of the batter's reach;
bye, an extra awarded if the batter misses the ball and it goes past the wicket-keeper and gives the batters time to run in the conventional way; and
leg bye, as for a bye except that the ball has hit the batter's body, though not their bat. •
caught – when a ball struck by the bat is caught by a fielder before it hits the ground •
leg before wicket – when the striker's body 'unfairly' prevents a delivery from hitting the wicket •
run out – generally when the ball is thrown at a wicket by a fielder while the batters are running between the wickets •
stumped – a special type of run out involving the wicket-keeper and striker Rare methods are: •
hit wicket – a striker hitting their own wicket •
hit the ball twice •
obstructing the field •
timed out – a batter failing to enter the field in a timely manner The Laws state that the fielding team, usually the bowler in practice, must appeal for a dismissal before the umpire can give their decision. If the batter is out, the umpire raises a forefinger and says "Out!"; otherwise, the umpire will shake their head and say "Not out". There is, effectively, a tenth method of dismissal,
retired out (self-dismissal – generally permanent except in cases of injury), which is not an on-field dismissal as such but rather a retrospective one for which no fielder is credited.
Bowling Most bowlers are considered specialists in that they are selected for the team because of their skill as a bowler, although some are all-rounders, and even specialist batters bowl occasionally. These specialists bowl "spells" that are generally 4 to 8 overs long in order not to physically exhaust the bowler, cause muscle strain and stress the skeleton. The rules prevent a single bowler from bowling consecutive overs, resulting in at least two bowlers alternating each over. If the captain wants a bowler to "change ends", another bowler must temporarily fill in so that the change is not immediate. Other fast bowlers rely on a mixture of speed and guile by making the ball
seam or
swing (i.e., curve) in flight. This type of delivery can deceive a batter into miscuing their shot, for example, so that the ball just touches the edge of the bat and can then be "caught behind" by the wicket-keeper or a slip fielder. In between the pacemen and the spinners are the medium-paced seamers, who rely on persistent accuracy to try to contain the rate of scoring and wear down the batter's concentration. Depending on their primary skills, the other ten players in the team tend to be classified as specialist batters or specialist bowlers. Generally, a team will include five or six specialist batters, and four or five specialist bowlers, plus the wicket-keeper.
Match closure There are a number of ways that a cricket match can end and its result be described, depending on whether the team batting first or last wins as well as the format of the game. If the team batting last is 'all out' having scored fewer runs than their opponents, they are said to have "lost by
n runs" (where
n is the difference between the aggregate number of runs scored by the teams). If the team that bats last scores enough runs to win, it is said to have "won by
n wickets", where
n is the number of wickets left to fall (batters yet to be dismissed) until the team would have been all out. For example, a team that passes its opponents' total having lost six wickets (i.e., six of their batters have been dismissed) wins the match "by four wickets", since the team would only have been prevented from scoring the winning runs if four more of its batters had been dismissed, which would have resulted in all but one of its eleven batters being dismissed. There have been instances of entire matches, even
Test matches scheduled to be played over five days, being lost to bad weather without a ball being bowled, for example, the third Test of the 1970/71 series in Australia.
Innings The innings (ending with 's' in both singular and plural form) is the term used for each phase of play during a match. Depending on the type of match being played, each team has either one or two innings. Sometimes all eleven members of the batting side take a turn to bat but, for various reasons, an innings can end before they have all done so. The innings terminates if the batting team is "all out", a term defined by the Laws: "At the
fall of a wicket or the retirement of a batter, further balls remain to be bowled but no further batter is available to come in". A match's
statistics are summarised on a
scorecard. Prior to the popularisation of scorecards, most scoring was done by men sitting on vantage points cuttings notches on
tally sticks, and runs were originally called notches. According to historian
Rowland Bowen, the earliest known scorecard templates were introduced in 1776 by T. Pratt of
Sevenoaks and soon came into general use. It is believed that scorecards were printed and sold at
Lord's for the first time in 1846. Scores are displayed differently depending on location, although it is standard to show how many wickets have been lost and how many runs a team has made. Within Australia, the format is Wickets/Runs, while in the rest of the world, the format is Runs/Wickets. For example, a score of 125 runs with 4 wickets lost would be displayed as 4/125 or 125/4, respectively.
Spirit of the Game Besides observing the Laws, cricketers must respect the "Spirit of Cricket", a concept encompassing
sportsmanship, fair play and mutual respect. This spirit has long been considered an integral part of the sport but is only nebulously defined. Amidst concern that the spirit was weakening, in 2000, a Preamble was added to the Laws instructing all participants to play within the spirit of the game. The Preamble was last updated in 2017, now opening with the line: The Preamble is a short statement intended to emphasise the "positive behaviours that make cricket an exciting game that encourages leadership, friendship, and teamwork". Its second line states that, "the major responsibility for ensuring fair play rests with the captains, but extends to all players, match officials and, especially in
junior cricket, teachers, coaches and parents". The umpires are the sole judges of fair and unfair play. They are required under the Laws to intervene in case of dangerous or unfair play or in cases of unacceptable conduct by a player. Previous versions of the Spirit identified actions that were deemed contrary (for example, appealing knowing that the batter is not out), but all specifics are now covered in the
Laws of Cricket, the relevant governing playing regulations and disciplinary codes, or left to the judgement of the umpires, captains, their clubs and governing bodies. The terse expression of the Spirit of Cricket now avoids trying to enumerate the diverse cultural conventions that exist in the detail of sportsmanship, or its absence. ==Women's cricket==
