What is true if a pitcher is replaced during a game?

When a pitcher is replaced during a game, the rules allow for the possibility of their return under specific conditions. This means that if all requirements set by the governing rulebook are met, a substituted pitcher can come back into the game. These conditions often pertain to factors like the type of substitution made (for instance, if it is a temporary substitution for a defensive replacement versus an injury) and the status of the game.

Understanding this allows for strategic management of a pitching staff, particularly in games where a pitcher may be removed for various tactical reasons, such as matchup advantages against specific batters or conserving pitch counts. The other options imply a more rigid approach to substitutions, which doesn't align with the rules that permit the return of a pitcher in certain scenarios.
