i think i do agree with this. he is using up the bullpen and this is where arms of Aceves/Doubront would be amazing.
both Doubbie and Aceves could chew up innings in meaningless games, and Tazawa Koji can be used for better games IMO.
and that would mean the 5th starter would be Webster. this should happen if Doubbie keeps failing to go beyond 5 innings, problem is Webster might have the same issue, but then you have Aceves/Doubs to go multiple innings. which currently we only have Mortensen to rely upon.
oh and when is Morales coming back.
