A courtesy runner in baseball is a player who is designated to run for another player on the basepaths. This is typically done to give a player who is slower or injured a chance to stay in the game without risking further injury or slowing down the pace of the game.
The use of a courtesy runner is allowed in some youth and amateur leagues, but it is not permitted in professional baseball or at the high school or collegiate level.
When a courtesy runner is used, the player who is being replaced remains in the game and continues to play their position in the field. The courtesy runner typically comes into the game only when the player they are replacing reaches base, and they are usually chosen from the bench or from a list of designated runners.
The rules governing the use of a courtesy runner can vary depending on the league or organization, so it is important to check with the appropriate governing body for specific guidelines and regulations.
Overall, the use of a courtesy runner is a way to provide flexibility and support for players who may be struggling with injuries or other physical limitations, while still allowing them to participate in the game and contribute to their team’s success.
