<P> Four 19th - century pitchers are known to have thrown with both hands: Tony Mullane in 1882 and in 1893, Elton Chamberlain in 1888, Larry Corcoran in 1884, and George Wheeler . </P> <P> Greg A. Harris was one of few major league pitchers in the modern era to pitch with both his left and his right arm, though he only did so in a single Major League game . A natural right - hander, by 1986 he could throw well enough left - handed that he felt capable of pitching with either arm in a game . Harris did not throw left - handed in a regular - season game until September 28, 1995, the penultimate game of his career . Pitching for the Montreal Expos against the Cincinnati Reds in the ninth inning, Harris retired Reggie Sanders pitching right - handed, then switched to his left hand for the next two hitters, Hal Morris and Ed Taubensee, who were both left - handed batters . Harris walked Morris but got Taubensee to ground out . He then went back to his right hand to retire Bret Boone to end the inning . </P> <P> Pat Venditte regularly pitches with both arms . Venditte was drafted by the New York Yankees, played for the Seattle Mariners, and now plays for the Philadelphia Phillies . While with the Staten Island Yankees, the Yankees' Single - A affiliate, when he opposed switch hitter Ralph Henriquez, Venditte switched his modified glove to his left arm . (Hitters traditionally derive advantages from batting from the opposite side of the plate to the pitcher's throwing arm .) Henriquez then switched to batting left - handed, and a series of changes continued for several minutes . This prompted the PBUC (Professional Baseball Umpires Corporation) to issue a new rule about switch - pitching . In short, switch - pitchers must indicate to the umpire, batter, and any runners the hand with which they will use to pitch . The pitcher must continue using this hand for the duration of the at bat, with some exceptions for injury and the use of pinch hitters . Following this choice, batters can then select with which hand they will bat . </P> <P> Right - handed pitcher Yu Darvish throws with his left hand when training . He does this to keep both arms strong and balanced . He does not pitch left - handed during a game, however . </P>
