"Law 13: Innings". Before the game, the teams agree whether it is to be one or two innings for each side, and whether either or both innings are to be limited by time or by overs. In practice, these decisions are likely to be laid down by Competition Regulations, rather than pre-game agreement. In two-innings games, the sides bat alternately unless the follow-on (Law 14) is enforced. An innings is closed once all batsmen are dismissed, no further batsmen are fit to play, the innings is declared or forfeited by the batting captain, or any agreed time or over limit is reached. The captain winning the toss of a coin decides whether to bat or to bowl first.
