The only explanation I have come to is that it has something to do with delaying his arbitration. There is absolutely no other reason guys like Marshall and Marmol should be pitching right now while Hill continues to dominate AAA.
Sure, the kid has struggled in his call-ups, but with this season already down the drain, it's time to call him up and give him regular work. How long has it been since the Cubs had a serviceable lefty in their rotation? Hibbard in '03?
The rotation after the AS break should be as follows...
Marshall needs to be shut down before his arm falls off. Let him work on 6 days rest and minimum innings in the minors, then call him back when Maddux gets dealt.
Anyone have insight on this? Is there really any reason why Rich Hill should still be pitching in Des Moines?
