The Arizona Diamondbacks shook up the back end of their starting rotation. Randall Delgado was sent to the bullpen while the team brought super reliever Josh Collmenter into the starting rotation. The move comes as Collmenter rescued the D’backs’ pitching staff Wednesday evening while Delgado gave the bullpen a workout Thursday with yet another rough outing. The question isn’t was this a smart move by the team. The question is, was this the correct move?
Over the past two seasons, Collmenter has been the valuable member of the pitching staff, with his ability to bail out his team with long outings. He also can pitch more than an inning on consecutive days. The role suits Tomahawk perfectly as he is not really a guy who can get through the an order three times. Moving him to the rotation turns a strength into a weakness. Delgado is going to the ‘pen to work on his issues. Is anyone confident that he can develop into the weapon that Collmenter was in that role? A better solution would have been to promote one of the starters at Triple A Reno not named Archie Bradley. Specifically, Charles Brewer who pitched in four games for the D’backs in 2013, or Bo Schultz, who pitched an inning in Australia; either of them couldn’t be any worse than what the team was getting out of Delgado.
The leash has to be short on Trevor Cahill as well. Perhaps that is who Schultz and/or Brewer will be taking the place of if he suffers through another miserable outing. That spot would be a little more permanent than the fifth starer’s spot. Hopefully, the experiment of Collmenter in the rotation is a short one. He is desperately needed in the bullpen.
