Why Do Managers Use a Pinch Runner for a Catcher?
A few extra feet of speed can change the entire inning.
Catchers spend much of the game squatting, blocking pitches, and managing pitchers. As a result, they are rarely selected primarily for speed.
Late in close games, a manager may decide that replacing a catcher with a faster runner creates a better chance of scoring from first on a double or from second on a single.
The decision carries consequences because the team must still have a catcher available for future innings. Managers rarely make the move unless the potential reward justifies the roster adjustment.
Pinch-running for a catcher reflects situational baseball. The value of speed temporarily becomes more important than the player's original role.
