http://espn.go.com/mlb/story/_/id/13018666/oakland-athletics-call-switch-pitcher-pat-venditte The Oakland Athletics have made the call for their bullpen, and they can go to either arm to bring in the major league's first ambidextrous pitcher since 1995. The A's purchased the contract of Pat Venditte from Triple-A Nashville on Friday, according to MLB.com. Venditte, who has a 2.37 ERA in 417 2/3 innings over eight minor league seasons, throws a fastball, slider and changeup from both sides and uses an ambidextrous glove with two thumb holes. He ranks fourth among Pacific Coast League pitchers, having allowed a .162 opponent batting average -- including just .092 against left-handed batters.
