I know you see a starter in Wilhelmsen, but there is value to leaving well enough alone :) He is six weeks removed from starting in AA and doing it extremely poorly. Maybe he's figured something out that he can implement on the mound no matter what his role is, but maybe he is mentally/emotionally better suited to relief pitching.
A relief pitcher has to be able to deal with the stress and anxiety of high leverage situations, but a starter has to maintain a razor sharp focus for 2+ hours. That is hard. Ever try to sit through a 2+ hour lecture without loosing focus? UGH!
