Twins general manager Terry Ryan has indicated that Rafael Perez is dealing with some soreness in his surgically-repaired left shoulder.
It sounds like normal post-op soreness, but it's keeping Perez from throwing off a mound. The southpaw is currently long-tossing from 90 feet. Perez entered camp as a possible candidate for the rotation, but at this point he'd probably be lucky to win a long relief job.
