Pat Venditte

Venditte is a switch pitcher, capable of pitching proficiently with both arms. He is recognized as the only active professional pitcher who is able to do this. Venditte's rare ability to pitch with either arm required both Major and Minor League Baseball to create a rule for ambidextrous pitchers, known colloquially as the ``Pat Venditte Rule''. This rule essentially requires any ambidextrous pitcher to declare which hand he will use to pitch to a batter before the at-bat starts, and to throw with that hand through the entire at-bat (unless he is injured during the at-bat).
