Innings Pitched is a statistic in baseball that measures the number of innings a pitcher has completed during a game or over a season. Each inning consists of three outs for the opposing team, and a pitcher is credited with one inning pitched for every full inning they complete. If a pitcher leaves the game before completing an inning, they receive a fraction of an inning based on how many outs they recorded. This statistic is important for evaluating a pitcher's performance and durability. It helps teams understand how much work a pitcher can handle and is often used in conjunction with other metrics, such as Earned Run Average (ERA) and Strikeouts.
