It was a no-brainer that Austin Jackson (abdominal strain) was coming back from the disabled list after a short rehabilitation stint.

But the Tigers also announced Saturday that Jhonny Peralta was put on the paternity list, so he could join his wife, Molly, for the birth of their second child.

The Tigers announced they were calling up Hernan Perez from Single-A Lakeland to take Peralta's spot on the roster, and not just because he's on the next page of the media guide. He's also on the 40-man roster, meaning that the team wouldn't need to clear room to add him, like they might a more experienced player.

A Midwest League all-star with Low-A West Michigan last year, Perez is hitting .252 with five-extra base hits in 55 games at Lakeland.

The team waited to make its second corresponding move to clear room on the 25-man roster for Jackson, likely to see the status of reliever Octavio Dotel, who was held out of Friday's game with inflammation in his pitching elbow. [UPDATED: The Tigers sent relief pitcher Jose Ortega back to Triple-A Toledo, restoring the proper pitcher/position player ratio on the roster.]

That move was roster transaction No. 25 for the Tigers already this season (11 in April, nine in May, and five already in June). The team has used 40 players total. If Perez gets in a game, he'll be the 21st position player to take the field for the Tigers.

Detroit has used the disabled list eight times since the season started, as well as the paternity list, the bereavement list and the restricted list once each. They've also designated three players for assignment, and released one more.

Brayan Villarreal has personally been called up three times, and sent down twice. Danny Worth has been up and down two times each. Once (May 17), the transaction was one for the other.
