Laws of Cricket: Match Structure - Batting, Run Scoring, Extras

Batting

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.

Run scoring

To score a run, a striker must run to the opposite end of the pitch, while his non-striking partner runs to his end. To register a run, both runners must touch the ground behind the crease with either their bats or their bodies (the batsmen carry their bats as they run). If the striker hits the ball well enough, the batsmen may double back to score two or more runs. However, no rule requires the batsman to run upon striking the ball. The decision to attempt a run is ideally made by the batsman who has the better view of the ball's position, and this is communicated by calling: "yes", "no" and "wait" are often heard. The batsmen swap ends every time an odd number of runs are scored.

If a fielder knocks the bails off the stumps with the ball while no part of the batsman is grounded behind the popping crease, the batsman nearer the broken wicket is run out. The batsman may ground the bat, provided he or she is holding it.

If the ball reaches the boundary, then runs are automatically scored: six if the ball goes over the boundary without touching the ground, four if it touched the ground. These are scored instead of any runs the batsmen may have already run (unless they have run more, which is unlikely), and they return to the ends at which they started.

Extras

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

Every run scored by the batsmen contributes to the team's total. A team's total also includes a number of runs which are unaccredited to any batsmen. These runs are known as extras; in Australia they are also called "sundries".
