Pinch runner

A pinch runner is a player who acts as a substitute to replace any baserunner who is already active on a base on the field. Once per inning, the offensive team are permitted to utilize one player who isn’t in the batting order to act as a pinch runner against any player on the opposing team. The player who was substituted out of the game is no longer allowed to return to play.

When Are Pinch Runners Used in a Baseball Game?

Pinch runners can be substituted into the game at any base, and are usually called upon when the active runner is slow or if the offensive team intends to attempt a steal using a fast runner. In rarer circumstances, they can be utilized to replace a runner in between bases if the active runner was expected to reach the next base safely but is unable to finish the run due to an injury.
