Cricket is a bat-and-ball game played between two teams of eleven players on a field, at the centre of which is a rectangular 22-yard-long pitch with a wicket (a set of three wooden stumps) erected at each end. One team, designated as the batting team, attempts to score as many runs as possible, whilst their opponents field. Each phase of play is called an innings. After either ten batsmen have been dismissed or a fixed number of overs have been completed, the innings ends and the two teams then swap roles. The winning team is the one that scores the most runs.
