Third of an inning

A third of an inning, a key term in baseball, is when a pitcher records one out before being replaced . This term plays a significant role in accurately measuring a pitcher’s performance and statistics, particularly when they have a short appearance in the game. In baseball, each inning is divided into three sections: the upper half, when the visiting team batters, and the bottom half, when the host team bats. A third of an inning represents a swift yet crucial contribution by a pitcher to the game, whether it involves securing a vital out or concluding an inning.
