Why not put Damon on the 15-day disabled list retroactive to Monday just as a precaution? Melky would be just fine in center field. That's why we have him. Damon is too valuable to take a chance with trying to "heal while he plays" like we did last year, and unless it is just a little tenderness (try a little tenderness?), then I'd shelve him for the time being. He'd come back just in time for the big push in mid-April against the Indians and Red Sox.
