The Pirates do have better starting pitching but there are many lumps to get over in this spot. Ian Snell has struggled this year with a 2-7 record and an ERA that he would prefer to be A LOT lower. The number five spot in the rotation is still yet to be decided. Charlie Morton struggled in his second start in the majors for the pirates vs. the Rockies.
Todd Wellemeyer would be a great fit. He would be a potential 15 game winner. Horacio Ramirez would also be a good fit. Not because of his numbers but because he is a veteran.
