Jim Bowden of MLB Network Radio reports that the Diamondbacks are discussing the possibility of moving Josh Collmenter to the bullpen once one of their young starters is ready. Collmenter posted a 3.59 ERA in 24 starts for the D'Backs last season, but he started to get hit harder once opposing hitters got used to his delivery, and his long-term role is probably as a reliever. Trevor Bauer in particular has really impressed the team not only with his stuff but with his work ethic, and he's nearly big league-ready. Tyler Skaggs isn't far off, either. Collmenter isn't a recommended option in mixed leagues this season.
