"Inning jail" is a commonly used term in baseball that refers to a scoreless half-inning where no runs are scored by the offensive team. However, there are several synonyms that can be used to describe this event, such as "clean inning," "shutout inning," or "perfect inning." All these terms emphasize the same idea: the pitcher successfully prevented the opposing team from scoring any runs during the inning. These synonyms are useful for commentators, analysts, and fans who want to describe the performance of a pitcher or the overall game in a more interesting and varied way.
