Other roles

Captain
For more details on this topic, see Role of a cricket captain.

The captain's acumen in deciding the strategy is sometimes crucial to the team's success. The captain makes a number of important decisions, including setting fielding positions, alternating the bowlers and taking the "toss". Before the start of play the captains of the opposing teams meet and toss a coin; the winner of the toss decides which team will bat first. This decision, made in consideration of pitch conditions, the weather and the relative bowling and batting abilities of the two sides, can have an enormous impact on the course of play. In One Day Internationals the captain also decides when to make use of some powerplays.

Runners
For more details on this topic, see runner (cricket).

In the event of a batsman being fit to bat but too injured to run, the umpires and the fielding captain may allow another member of the batting side to be a runner. If possible, the runner must already have batted. The runner's only task is to run between the wickets instead of the injured batsman. The runner is required to wear and carry exactly the same equipment as the incapacitated batsman. It is possible for both batsmen to have runners, but this is extremely rare.

Substitutes
For more details on this topic, see Substitute (cricket).

In all forms of cricket, if a player gets injured or becomes ill during a match, a substitute is allowed to field instead of him, but the substitute cannot bowl, bat, act as a captain or wicket-keeper. The substitute leaves the field if the injured player is fit to return.

For a period from July 2005, the ICC experimented with Super Subs in One Day International (ODI) cricket and some other limited-overs competitions. A single full substitution was allowed, and the substituted player was not allowed to return to the game. It was discontinued from March 2006.

Laws of cricket

The game is played in accordance with 42 laws, which have been developed by the Marylebone Cricket Club in discussion with the main cricketing nations. Teams may agree before a game to introduce other rules or alter some of the existing rules. In particular, there are a number of modifications to rules dictating fielding positions for professional limited overs matches.

Players and officials

Players

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. 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; most players focus on either batting or bowling skills.

Umpires
For more details on this topic, see Umpire (cricket).

Two on-field umpires preside over a match. One umpire stands behind the bowler's wicket, and adjudicates on most decisions. The other (the "square leg umpire") stands with a side view of the batsman (usually near the fielding position called square leg), and assists in decisions for which he or she has a better view. In some professional matches the facility exists for them to refer some decisions to a third umpire, who has the assistance of television replays. In international matches a match referee ensures that play is within the laws of cricket and the spirit of the game. The third umpire and referee do not take the field during play.

Scorers
For more details on this topic, see Scorer.

Two scorers are appointed; usually, one is provided by each team. The laws of cricket specify that the official scorers are to record all runs scored, wickets taken and (where appropriate) overs bowled. They are to acknowledge signals from the umpires, and to check the accuracy of the score regularly both with each other and, at playing intervals, with the umpires. In practice scorers also keep track of other matters, such as bowlers' analyses, the rate at which the teams bowl their overs, and team statistics such as averages and records. In international and national cricket competitions, the media often require notification of records and statistics, so unofficial scorers often keep tally for broadcast commentators and newspaper journalists. The official scorers occasionally make mistakes, but unlike umpires' mistakes these can be corrected after the event.

The playing field
For more details on this topic, see Cricket field.

The cricket field consists of a large, often circular or oval-shaped, grassy ground. There are no fixed dimensions for the field but its diameter usually varies between 450 feet (137 m) and 500 feet (150 m). The perimeter of the field, known as the boundary, is marked, often with a rope or a painted line.

The pitch
For more details on this topic, see Cricket pitch.
A wicket consists of three stumps that are hammered into the ground, and topped with two bails.

Most of the action takes place in the centre of this ground, on a rectangular clay strip usually with short grass called the pitch. The pitch measures 10 × 66 feet (3.05 × 20.12 m). The longer dimension of the pitch is also a unit of length known as a chain.

At each end of the pitch three upright wooden stakes, called the stumps, are hammered into the ground. Two wooden crosspieces, known as the bails, sit in grooves atop the stumps, linking each to its neighbour. Each set of three stumps and two bails is collectively known as a wicket. One end of the pitch is designated the "batting end" where the batsman stands and the other is designated the "bowling end" where the bowler runs in to bowl.

The area of the field on the side of the line joining the wickets where the batsman holds his bat (the right-hand side for a right-handed batsman, the left for a left-hander) is known as the "off side", the other as the "leg side" or "on side".

Lines drawn or painted on the pitch are known as creases. Creases are used to adjudicate the dismissals of batsmen and to determine whether a delivery is legal.

The nature of the pitch

Pitches vary in consistency, and thus in the amount of bounce, spin, and seam movement available to the bowler. Hard pitches are usually good to bat on because of high but even bounce. Dry pitches tend to deteriorate for batting as cracks often appear, and when this happens spinners can play a major role. Damp pitches, or pitches covered in grass (termed "green" pitches), allow good fast bowlers to extract extra bounce and seam movement. Such pitches tend to offer help to fast bowlers throughout the match, but become better for batting as the game goes on.

Parts of the field

For some limited-over matches, there are two additional field markings. A painted oval is made by drawing a semicircle of 30 yards (27.4 m) radius from the centre of each wicket with respect to the breadth of the pitch and joining them with lines parallel, 30 yards (27.4 m) to the length of the pitch. This line, commonly known as the "circle", divides the field into an infield and outfield. Two circles of radius 15 yards (13.7 m), centred on each wicket and often marked by dots, define the "close-infield". The infield, outfield, and the close-infield are used to enforce fielding restrictions.

Placements of players
For more details on Fielding positions, see fielding positions in cricket.
Fielding positions in cricket for a right-handed batsman. The named positions are only indicative: the fielders may stand anywhere. The bowler and wicket-keeper are always in roughly the same position, and there are only nine other fielders, so there are always many unprotected areas.

The batting team always has two batsmen on the field. One batsman, known as the "striker", faces and plays the balls bowled by the bowler. His or her partner stands at the bowling end and is known as the "non-striker".

The fielding team has eleven players on the ground. One of them is the current bowler. The wicket-keeper, who generally acts in that role for the whole innings, stands or crouches behind the wicket at the batting end. The captain of the fielding team spreads his or her remaining nine players — the fielders — around the ground, positioned according to the team's strategy.

Match structure

The toss
For more details on this topic, see toss (cricket).

The two opposing captains toss a coin before the match, and the captain who wins chooses either to bat or bowl first. The captain's decision is usually based on whether the team's bowlers are likely to gain immediate advantage from the pitch and weather conditions (these can vary significantly), or whether it is more likely that the pitch will deteriorate and make batting more difficult later in the game.

Overs
For more details on this topic, see Over (cricket).

Each innings is divided into overs, each consisting of six consecutive legal deliveries bowled by the same bowler. For the definition of illegal deliveries, see Extras. No bowler may bowl two consecutive overs, so at the end of the over the bowler takes up a fielding position and another player bowls.

Overs are bowled from alternate ends of the pitch; at the end of each over the umpires swap, the umpire at the bowler's end moving to square leg, and the umpire at square leg moving to the new bowler's end. The fielders also usually change positions.

End of an innings
For more details on this topic, see End of an innings (cricket).

An innings is completed if:
Ten out of eleven batsmen are out (dismissed); the team are said to be "all out".
The team has only one batsman left who can bat, one or more of the remaining players being unavailable owing to injury, illness or absence; again, the team is said to be "all out".
The team batting last reaches the score required to win the match.
The predetermined number of overs has been bowled (in a one-day match only, most commonly 50 overs).
A captain declares his team's innings closed (this does not apply in one-day limited over matches).

Playing time
For more details on this topic, see Playing time (cricket).

Typically, two-innings matches are played over three to five days with at least six hours of cricket played each day. One-innings matches are usually played in one day, and often last six hours or more. There are usually formal intervals on each day for lunch and tea, and brief informal breaks for drinks. There is also a short interval between innings.

The game is usually only played in dry weather; play is also usually stopped if it becomes too dark for the batsmen to be able to see the ball safely. Some one-day games are now played under floodlights but, apart from a few experimental games in Australia, floodlights are not used in longer games. Professional cricket is usually played outdoors. These requirements mean that in England, Australia, New Zealand, South Africa and Zimbabwe the game is usually restricted to the summer. In the West Indies, India, Pakistan, Sri Lanka and Bangladesh games are played in the winter. These countries' hurricane and monsoon seasons coincide with their summer.

Batting

Main articles: batsman and batting (cricket)

The batsman may play a "shot" or "stroke", attempting to hit the bowled ball with the flat surface of the bat. If the ball brushes the side of the bat it is called an "edge". There is no requirement for the batsman to play a shot, and there is no requirement to run if the ball is struck. The batsman automatically scores runs if he hits the ball to the boundary. Shots are named according to the style of swing and the direction aimed. As part of the team's strategy, the player may bat defensively, blocking the ball downwards, or aggressively, hitting the ball hard to empty spaces in order to score runs.

Batsmen come in to bat in a batting order, decided by the team captain. The first two batsmen - the "openers" - usually face the most hostile bowling, from fresh fast bowlers with a new ball. The top batting positions are usually given to the most competent batsmen in the team, and the non-batsmen typically bat last. The batting order is not agreed beforehand, and if a wicket falls any player who has not batted yet may bat next.

Results

If the team that bats last is all out having scored fewer runs than their opponents, the team is said to have "lost by n runs" (where n is the difference between the 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. For instance a team that passes its opponents' score having only lost six wickets would have won "by four wickets".

In a two-innings-a-side match, one team's combined first and second innings total may be less than the other side's first innings total. The team with the greater score is then said to have won by an innings and n runs, and does not need to bat again: n is the difference between the two teams' aggregate scores.

If the team batting last is all out, and both sides have scored the same number of runs, then the match is a tie; this result is quite 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 declared 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 after its developers, is often used to recalculate a new target score. A one-day match can also 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, wet weather

Overview

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 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 hits the ball to the boundary of the playing area (this scores 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 like bowling the ball out of reach of the batsman.[4]

The aim of the bowler's team is to get each batsman out (this is called a "taking a wicket", or a "dismissal").[5] Dismissals are achieved in a variety of ways. The most direct way is for the bowler to bowl the ball so that the batsman misses it and it hits the stumps, dislodging a bail. While the batsmen are attempting a run, the fielders may 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 the ball off the bat before it touches the ground, or having the batsman adjudged "leg before wicket" (abbreviated "L.B.W." or "lbw") if the ball strikes the batsman's body and would have gone on to hit the wicket.[6] 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 referred to as a "ball" or a "delivery").[7]

The game is divided into overs of six (legal) balls. At the end of an over another bowler from the fielding side bowls from the opposite end of the pitch. The two umpires also change positions between overs (the umpire previously at square-leg becomes the bowler's umpire at what is now the bowling end, and vice versa). The fielders also usually change positions between overs.

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, leaving one batsman not out but without a partner. 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, and the side that has been fielding bats.

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

Cricket

Cricket is a bat-and-ball sport contested by two teams, usually of eleven players each.[1] 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 cricket pitch. A wicket, usually made of wood, is placed at each end of the pitch.

The bowler, a player from the fielding team, bowls a hard, fist-sized cricket 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 ball in an effort to stop the batsman scoring runs, and if possible to get him or her out. The batsman — if he or she does not get out — 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. Runs are also scored if the batsman hits the ball to the boundary of the playing area. The match is won by the team that scores more runs.

Cricket has been an established team sport for hundreds of years and is thought to be the second most popular sport in the world, after football (soccer).[2] More than 100 countries are affiliated to the International Cricket Council, cricket's international governing body. The sport's modern form originated in England, and is most popular in the present and former members of the Commonwealth. In many countries including Bangladesh, India, Pakistan, Sri Lanka and the English-speaking countries of the Caribbean, which are collectively known in cricketing parlance as the West Indies, cricket is the most popular sport. In Australia, while other sports are more popular in particular areas, cricket has been described as the "national sport" and has had a role in forming the national identity.[3] It is also a major sport in England, New Zealand, South Africa and Zimbabwe . Many countries also have well-established amateur club competitions, including the Netherlands, Kenya, Nepal and Argentina.

The sport is followed with passion in many different parts of the world. It has even occasionally given rise to diplomatic outrage, notoriously the Basil D'Oliveira affair (which led to the banning of South Africa from sporting events) and the Bodyline Test series in the early 1930s (which led to a temporary deterioration in relations between Australia and the United Kingdom).
