Red Sox's Triston Casas: Takes swings in batting cage

Casas (ribs) took approximately 20 swings in the batting cage Wednesday at about 75-percent effort, Molly Burkhardt of MLB.com reports.

Casas resumed hitting for the first time since he was diagnosed with a cartilage tear in his left ribcage in late April. He said he felt great during the workout, but he noted that the real test will be to see how sore he is Thursday. If Casas isn't experiencing too much discomfort Thursday, he could be cleared to start hitting off a tee. Casas undoubtedly will require a rehab assignment before returning from the 60-day injured list, and it's uncertain when he might be ready for game action.
