A cricket match is played on a cricket field at the centre of which is a pitch. The match is contested between two teams of eleven players each. One team bats, trying to score as many runs as possible without being dismissed ("out") while the other team bowls and fields, trying to dismiss the other teamís batsmen and limit the runs being scored. When the batting team has used all its available overs or has no remaining batsmen, the roles become reversed and it is now the fielding teamís turn to bat and try to outscore the opposition.
