Pinch Run

[gmtomko]

Fed rules would consider this a substitution and re-entry would be possible for the player that the pinch runner replaced.

Courtesy runners are allowed for the pitcher or catcher at any time they are on base if the speed-up rules are adopted by the state. The restriction is that a single courtesy runner cannot run for both the pitcher and catcher in the same half inning and they cannot be in the game in any other capacity (starter or sub) at the time they are used.
