Melky Cabrera has done a nice job of late, but if the Yankees are going to be without Gary Sheffield for a long period of time, I have little doubt that they'll be in the market for another outfielder before the trading deadline. Several days ago, Will Carroll had the following to say about Sheff over at Baseball Prospectus:

The injury to Gary Sheffield is devastating. I dug and dug to get the information on what was actually going on with Sheffield, knowing that while the Yankees were not lying about the injury, they weren't giving anyone the whole story. Just as I was putting the pieces together, having two of my best advisors pointing me in what was the correct direction, Sheffield's wrist made my work moot. Sheffield's injury was not a bruise or a fracture, but a soft tissue injury. The torn ligament and translocated tendon have only an outside chance of repairing themselves without surgical intervention, but the chance that they could--along with the timetable of surgery--means it makes sense to wait. If Sheffield had surgery now, he wouldn't be back in time for the playoffs and waiting a month just pushes it a bit further into the off-season. Yes, you'll note that if he waits that will possibly affect him next season, but that's not really the Yankees' concern given his contract situation--or is there some handshake agreement that helped Sheffield stay patient on the chance he gets better? We don't know. Sheffield has a small chance of avoiding surgery, so adjust your expectations accordingly.

It'll be interesting to see what the Yankees do, huh?
