In baseball, a pinch hitter is a substitute batter. Batters can be substituted at any time while the ball is dead (not in active play); the manager may use any player who has not yet entered the game as a substitute. Unlike basketball, American football, or ice hockey, baseball does not have a "free substitution rule" and thus the replaced player in baseball is never allowed back into that game. The pinch hitter assumes the spot in the batting order of the player they replace.
