By pulling him in the fifth you now have to get outs in the fifth, sixth, and seventh to get to Whitlock and Chappy! Who in the bullpen is going to get those outs. If you had Slaton and Guerrero for the Sixth and seventh then maybe you can bring in Miller in the fifth. I would have rolled the dice with Tolle to get out of the fifth. Probably throws 90 plus pitches by that point and then bring in Miller in the sixth.
