Here is how switch-pitcher Pat Venditte’s card (OAK Venditte) is designed to be used:
- When facing a batter who is not a switch hitter Venditte is considered to be throwing from the same side as the hitter (RH vs RHB, LH vs LHB).
- When facing a switch-hitter Venditte throws LH and uses his italicized fatigue numbers while the batter hits RH. There is a SPECIAL on Venditte’s card as a reminder. Note: facing a switch-hitter does not cause Venditte to fatigue, he is just forced to use the italicized numbers.
- Venditte fatigues based on total batters faced. When he reaches his limit he is fatigued regardless of which arm is being used. Similarly, Venditte’s BF totals for rest purposes are cumulative regardless of which arm was being used.
- If Venditte is injured he is considered unable to pitch for the duration of the injury regardless of which arm was being used at the time of injury.
For reference purposes, the MLB rule covering Venditte is Rule 5.07(f) [formerly 8.01(f)]:
A pitcher must indicate visually to the umpire-in-chief, the batter and any runners the hand with which he intends to pitch, which may be done by wearing his glove on the other hand while touching the pitcher’s plate. The pitcher is not permitted to pitch with the other hand until the batter is retired, the batter becomes a runner, the inning ends, the batter is substituted for by a pinch-hitter or the pitcher incurs an injury. In the event a pitcher switches pitching hands during an at-bat because he has suffered an injury, the pitcher may not, for the remainder of the game, pitch with the hand from which he has switched. The pitcher shall not be given the opportunity to throw any preparatory pitches after switching pitching hands. Any change of pitching hands must be indicated clearly to the umpire-in-chief.
