other arm to rest the arm he just pitched with. Judson University hurler Ryan Perez made national headlines in 2014 playing collegiate summer baseball with the Hyannis Harbor Hawks of the Cape Cod Baseball League. Perez took home the league's annual All-Star Game MVP award after a dominating performance pitching from both sides. Training methods Switch-throwers are commonly taught to switch-throw at a young age. For instance, Venditte's father trained him in ambidextrous throwing from the age of three and Brunnig's father taught him from age five. Controversy In 2008, while with the Staten Island Yankees, the New York Yankees' Single-A affiliate, switch pitcher Pat Venditte 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 Professional Baseball Umpires Corporation (PBUC) to issue a new rule about switch-pitching. In short, switch pitchers must indicate to the umpire, batter, and any runners the hand 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. References Further reading The Associated Press. "Ambidextrous pitcher stars at Creighton". MSNBC, May 3, 2006.
