Courtesy Runner

Also known as: courtesy runner rule, CR

Definition

A courtesy runner is a substitute allowed to run the bases for a player who reaches base but is unable to run. That player stays in the game; common reasons include injury, age-based recreational-league eligibility, or a pitcher/catcher who needs rest between innings.

Recreational slow-pitch leagues, especially those with older or mixed-ability rosters, commonly allow a courtesy runner. The rule exists so that a player who cannot run at full speed does not have to be pulled from the lineup entirely. That includes a valued hitter or a player nursing a minor injury. Rules vary on exactly who qualifies and how often a courtesy runner can be used per inning or per game. Some leagues cap it to a specific number of instances. Others allow it freely for a designated "slow runner" role set before the game.

The courtesy runner replaces the batter or baserunner only for baserunning purposes. The original player remains in the batting order and returns to their fielding position as normal. Teams should confirm their specific league's courtesy-runner limits before the game. Overusing it beyond the allowed count can result in an out or other penalty, depending on the rule set.

Example

The team's power hitter, playing through a minor ankle tweak, reaches base on a double. A courtesy runner enters to run the bases while she stays in the lineup for her next at-bat.

Why it matters

Understanding courtesy-runner limits keeps recreational teams from losing an out or facing a rule violation over a well-intentioned substitution. SwingVantage's rules glossary helps newer players and captains navigate these recreational-league-specific accommodations.

Frequently asked questions

Does using a courtesy runner remove the original player from the game?

No. The original player stays in the batting order and returns to the field on defense. The courtesy runner only substitutes for baserunning on that specific time on base.

Is there a limit on how many times a team can use a courtesy runner?

Most recreational leagues cap it — commonly once per player per inning or a fixed number of total uses per game — so teams should confirm the specific limit with their league before relying on it.
