DETROIT -- Freddy Garcia was at Comerica Park on Saturday morning for a workout and a meeting with manager Jim Leyland, but details regarding a potential callup remain scarce.

Leyland said that if anything is going to happen, it will happen soon.

"It's just a combination of working out some details," Leyland said. "I believe we'll have, probably -- most likely -- some announcements [on Sunday] on our callups."

Rosters expand on Monday, and Leyland's announcement may or may not include Garcia, who signed a Minor League contract with the Tigers on Aug. 12.

In order to be promoted to the big league club, Garcia would need to be added to the 40-man roster. At that point, the Tigers would have to extend his contract, or he would become a free agent this offseason.

Dialogue about a possible extension was not part of Garcia's conversation with the manager on Saturday morning, Leyland said.

Monday will mark a one-year anniversary of sorts for the right-hander, who had his shoulder surgery on Sept. 1 of last year. Though he may never throw the 94-95 mph that he once did, Garcia isn't going to change his approach on the mound.

"I don't think he's gonna change the way he pitches," Leyland said. "I wouldn't expect a guy that has labrum and rotator cuff [injuries] to throw 95 again. I guess it does happen, but I wouldn't expect it."

Garcia will not throw anymore in the Minor Leagues because those seasons are ending, so the only other opportunity to pitch before a possible winter ball season will be with the Tigers in September.

"It certainly appears that he's determined to try and pitch again," Leyland said. "His desire to do that again is obviously there."
