What impressed me most with Rauch this season was his 0.99 Whip but that can be mostly explained to the very low .222 BABIP that he had this year. His walk rate was at an all time low this year at 1.87 BB/9. His velocity hasn't decreased so there aren't any real concerns there. You know what? With the starting rotation that we have at this point, we could use all the bullpen help that we can get and he would probably be a good candidate for set-up man.
