Daric Barton had an MRI exam earlier in the week after developing soreness in his surgically repaired right shoulder. Barton underwent surgery in September to repair a partial labrum tear. "Everything looked good, so I'll get back into it slowly," Barton said. "The biggest thing for me was to find out that it's fine.'' Barton is not expected to throw until mid-March, and now possibly later than that. He'll look to reclaim his old role as a starter when healthy.
