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.

A perspective view of the cricket pitch from the bowler's end. The Cricket pitch dimensions
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:

1. Ten out of eleven batsmen are out (dismissed); the team are said to be "all out".
2. 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".
3. The team batting last reaches the score required to win the match.
4. The predetermined number of overs has been bowled (in a one-day match only, most commonly 50 overs).
5. 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.
