"Finally we are back and we're going to give 100 percent to the team," Callaspo said.
To make room for Callaspo -- who has been on the disabled list with a right calf strain since April 19 -- infielder Andrew Romine was optioned to Triple-A Salt Lake.
Callaspo, who was hitting .273 in nine games this season, played the past three days on a rehab assignment with Class A Inland Empire where he went 2-for-7 with a home run.
"I was trying to work out and look for some pitches," Callaspo said of his rehab stint. "I came back quick. I just want to play here. It was sore [the first day back] but now it feels good."
Callaspo hit seventh and was in Friday's lineup at third base for the Angels.
