Run out is a method of dismissal in cricket, in which the fielding team put down the wicket of a batter who is outside their ground, usually because they are trying to score a run.
Run out is governed by Law 38 of the laws of cricket. If the batter is judged run out, the run does not count and the bowler does not get credit for the wicket.
A run out can also be effected when the batters are not attempting a run if one of them leaves the crease when the ball is not dead. Some such dismissals cause controversy because they challenge long-established — but not universal — conventions about the spirit of the game.
