The term 'Turns at Bat' is a baseball statistic that measures the number of times a batter has come to the plate in a game. It is also known as an At-Bat or AB. An Inning is a unit of play in baseball, consisting of two halves in which each team has a turn at bat. In each half, one team bats until three outs are made. Therefore, the number of Turns at Bat in an Inning is equal to the number of batters who have come to the plate before three outs are made.
