Oakland, Calif. • The Oakland Athletics have acquired third baseman Alberto Callaspo from AL West rival Los Angeles Angels for infielder Grant Green.
Callaspo was removed from the Angels' game against the Texas Rangers after the fourth inning on Tuesday night.
Callaspo was hitting .253 with five home runs and 36 RBIs entering Tuesday. He will likely play second base for the A's because Oakland has Josh Donaldson at third base. Callaspo last played second in 2010.
