Worcester should have a rotation filled with interesting starting pitchers next year: Fitts, Priester, Dobbins, maybe Penrod if they want to have him start again. Wikelman and Isaac Coffey could be in the rotation, but they seem less likely to help the big club as starters next year. Maybe Chris Murphy and/or Drohan? There's Mata, but if he's in the org I think they'd be better off using him in relief.
I don't think Criswell will have any options left so he probably won't be there, but still that's more AAA rotation depth than they've had in a while.
