Giants re-signed RHP Sandy Rosario to a minor league contract.

Rosario was released by the Giants last week but is now back in the organization on a restructured deal. The 28-year-old right-hander has not pitched in a minor league game this season because of a lingering leg injury.

Sandy Rosario has missed the last few days due to leg weakness.

"He's had an MRI, seen different doctors," Giants manager Bruce Bochy said. "He just doesn't have a lot of strength in his legs right now." Rosario was in street clothes in the Giants locker room Wednesday, and reports said he could barely walk as a result of the affliction. This doesn't help Rosario's chances of making the club out of spring.
