A Test match between South Africa and England in January 2005. The men wearing black trousers on the far right are the umpires. Test cricket, first-class cricket and club cricket are played in traditional white uniforms and with red cricket balls, while professional One-day cricket is usually played in coloured uniforms and with white balls.
A One-Day International match at The Melbourne Cricket Ground between Australia and India. The batsmen are wearing yellow, while the fielding team is wearing blue.Cricket is a bat-and-ball sport contested by two teams, usually of eleven players each. A cricket match is played on a grass field, roughly oval in shape, in the centre of which is a flat strip of ground 22 yards (20.12 m) long, called a pitch. At each end of the pitch is a construction of three parallel wooden stakes (known as stumps) driven vertically into the ground, with two small crosspieces (known as bails) laid across the top of them. This wooden structure is called a wicket.

The bowler, a player from the fielding team, hurls a hard, fist-sized, cork-centred, leather-covered ball from the vicinity of one wicket towards the other. The ball usually bounces once before reaching the batsman, a player from the opposing team. In defence of the wicket, the batsman plays the ball with a wooden cricket bat. Meanwhile, the other members of the bowler's team stand in various positions around the field as fielders, players who retrieve the batted ball in an effort to stop the batsman scoring, and if possible to get him or her out. The batsman, if he or she does not get out (for example if the bowled ball hits the wicket, or if a fielder catches the ball off the bat before it bounces), may run between the wickets, exchanging ends with a second batsman (the non-striker), who has been waiting near the bowler's wicket. Each completed exchange of ends scores one run, and the match is won by the team that scores more runs.

Cricket has been an established team sport for hundreds of years. It originated in its modern form in England and is most popular in the present and former members of the Commonwealth. Cricket is the second most popular sport in the world.[1][2][3] More than a hundred cricket-playing nations are recognised by the International Cricket Council.[4] In the countries of South Asia, including India, Pakistan, Bangladesh and Sri Lanka, cricket is the most popular sport. It is also a major sport in England and Wales, Australia, New Zealand, South Africa, Zimbabwe and the English-speaking countries of the Caribbean, which are collectively known in cricketing parlance as the West Indies. There are also well-established amateur club competitions in countries as diverse as the Netherlands, Kenya, Nepal and Argentina, among others.

The sport is followed with passion in many different parts of the world. It has even occasionally given rise to diplomatic outrage, the most notorious being the Basil D'Oliveira affair which led to the banning of South Africa from sporting events. Other examples include the Bodyline series, played between England and Australia in the early 1930s, and the 1981 underarm bowling incident involving Australia and New Zealand.

Overview

A traditional cricket ball. The white stitching is known as the seam.
As one-day games are often played under floodlights, a white ball is used to aid visibility.
A cricket bat, front and back sides.The aim of the batting team is to score as many runs as possible. A run is scored when both batsmen successfully move to their respective opposite ends of the pitch (the pitch is sometimes referred to as the "wicket", a term with multiple meanings). (The batsmen will usually only attempt to score runs after the striker has hit the ball, but this is not required by the rules—the batsmen can attempt runs at any time after the ball has been bowled.) Runs are also scored if the batsman propels the ball to the boundary of the playing area (scoring six runs if the ball crosses the boundary without having touched the ground or four runs otherwise), or if the bowler commits some technical infringement.

The aim of the bowler's team is to get each batsman out (this is a wicket, or a dismissal). Dismissals are achieved in a variety of ways. The most direct way is for the bowler to bowl the ball in such a way that it hits the stumps, dislodging the bails. While the batsmen are attempting a run, the fielders may attempt to dismiss either batsman by using the ball to knock the bails off the set of stumps to which the batsman is closest, before he has grounded himself or his bat in the crease. Other ways for the fielding side to dismiss a batsman include catching a struck ball before it touches the ground, or having the batsman adjudged LBW (leg before wicket, i.e. attempting to block the ball from hitting the stumps using his body, which is prohibited). Once the batsmen are not attempting to score any more runs, the ball is "dead" and is bowled again (each attempt at bowling the ball is a ball or a delivery).

The game is divided into overs of six (legal) balls. At the end of an over, the batting and bowling ends will be swapped, and the bowler replaced by another member of the fielding side. The two umpires also change positions at this time (the umpire previously at square-leg becomes the bowler's umpire at what is now the bowling end, and vice versa), and the fielding positions are rearranged.

Once out, a batsman is replaced by the next batsman in the team's line-up. (The batting side can reorder their line-up at any time, but no batsman may bat twice in one innings.) The innings (singular) of the batting team ends when the tenth batsman is given out, since there always must be two batsmen on the field. When this happens, the team is said to be all out. (In limited overs cricket the innings ends either when the batting team is all out or a predetermined number of overs has been bowled.) At the end of an innings, the two teams exchange roles, the fielding team becoming the batting team and vice versa.

A team's score is reported in terms of the number of runs scored and the number of batsman that have been dismissed. For example, if five batsmen have been given out and the team has scored 224 runs, they are said to have scored 224 for the loss of 5 wickets (shortened to "224 for 5" and written 224/5 or, in Australia, "5 for 224" and 5/224).

The team that has scored more runs at the end of the completed match wins. Different varieties of the game have different definitions of "completion"; for instance there may be restrictions on the number of overs, the number of innings, and the number of balls in each innings.


Results
Main article: The result in cricket
If the team that bats last has all of its batsmen dismissed before it can reach the run total of the opposing team, it is said to have lost by (n) runs (where (n) is the difference between the two run totals). If however, the team that bats last exceeds the opposing team's run total before its batsmen are dismissed, it is said to have won by (n) wickets, where (n) is the difference between the number of wickets conceded and 10.

If, in a two-innings-a-side match, one team's combined first and second innings total fails to reach its opponent's first innings total, there is no need for the opposing team to bat again and it is said to have won by an innings and (n) runs, where (n) is the difference between the two teams' totals.

If all the batsmen of the team batting last are dismissed with the scores exactly equal then the match is a tie; ties are very rare in matches of two innings a side. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is a draw.

If the match has only a single innings per side, then a maximum number of deliveries for each innings is often imposed. Such a match is called a limited overs or one-day match, and the side scoring more runs wins regardless of the number of wickets lost, so that a draw cannot occur. If this kind of match is temporarily interrupted by bad weather, then a complex mathematical formula known as the Duckworth-Lewis method is often used to recalculate a new target score. A one-day match can be declared a No-Result if fewer than a previously agreed number of overs have been bowled by either team, in circumstances that make normal resumption of play impossible—for example, an extended period of bad weather.


Laws of cricket
For more details on this topic, see Laws of cricket.
The game is played in accordance with 42 laws of cricket, which have been developed by the Marylebone Cricket Club in discussion with the main cricketing nations. Teams may agree to alter some of the rules for particular games. Other rules supplement the main laws and change them to deal with different circumstances. In particular, there are a number of modifications to the playing structure and fielding position rules that apply to one innings games that are restricted to a set number of fair deliveries.


Players and officials

Players
For more details on this topic, see Cricketer.
A team consists of eleven players. Depending on his or her primary skills, a player may be classified as a specialist batsman or bowler. A balanced team usually has five or six specialist batsmen and four or five specialist bowlers. Teams nearly always include a specialist wicket-keeper because of the importance of this fielding position. Of late, the role of specialist fielder has also become important in a team. Each team is headed by a Captain who is responsible for making tactical decisions such as determining the batting order, the placement of fielders and the rotation of bowlers.

A player who excels in both batting and bowling is known as an all-rounder. One who excels as a batsman and wicket-keeper is known as a wicket-keeper/batsman, sometimes regarded as a type of all-rounder. True all-rounders are rare and valuable players; most players focus on either their batting or their bowling.


Umpires
For more details on this topic, see Umpire (cricket).
Two on-field umpires preside over a match. One umpire (the bowler's umpire) will stand behind the wicket at the end from which the ball is bowled, and adjudicate on most decisions. The other (the square leg umpire) will stand near the fielding position called square leg, which offers a side view of the batsman, and assist on decisions for which he or she has a better view. In some professional matches, they may refer a decision to an off-field third umpire, who has the assistance of television replays. In international matches an off-field match referee ensures that play is within the laws of cricket and the spirit of the game.
