I'll take the easy way out, and say there's simply no way of knowing who will be needed from the system. Most common names I see here are Wang, Woodruff, and Burnes. Wang- IF Suter goes back to the pen they would already have 2 lefties, so they may not want to add Wang. But probably better than 50/50 chance he comes up at some point due to injury/ineffectiveness. Woodruff- By the time he's done with rehab, getting ramped up again, etc. it may be deep into August. Do you want to add him to the rotation at that point? Maybe, it all depends on how the back end of the rotation is performing. Once Anderson is back, you still have Guerra or Suter in the 5th spot, so this is really undecided. Burnes- We don't know his innings limit. I can't imagine they add him to the rotation and have him pitching into October. They would either need to shut him down now for a while, or add him to the pen. I don't think they'll mess with him like that. However, it would make perfect sense to bring him up to the pen when the roster expands.
