Green is playing for Triple-A Sacramento, where he is batting .325/.379/.500 with 11 home runs and 50 RBIs in 87 games. He was hitless in his only 15 at-bats for the A’s this season.
Callaspo was hitting .253 with five home runs and 36 RBIs as the Angels’ everyday third baseman. Last year he batted .252, the lowest batting average he’s had in a full season in his career. He is under contract through 2014 and the Angels could use the money saved to make multiple deals before tomorrow’s 1 p.m. non-waiver trade deadline.
Green attended Cal State Fullerton and Canyon High School in Anaheim. He was ranked as Baseball America’s 63rd-best prospect prior to the 2011 season.
Chris Nelson was pulled from the Triple-A Salt Lake Bees’ game against the Iowa Cubs, a strong indication that he will be recalled to take Callaspo’s spot on the 25-man roster.
