Josh Collmenter allowed four runs on seven hits over seven innings in a no-decision against the Rockies on Wednesday. He struck out two and walked a pair. Collmenter would have been fine if he'd avoided the long ball, but that's no easy proposition against the Rockies. One homer -- Carlos Gonzalez's two-run first inning dinger -- wasn't upsetting, but Jordan Lyles' solo shot in the third stung. Collmenter didn't join the rotation until April 14, but he's arguably been Arizona's best starter so far (insert your own joke here). That doesn't mean you should use him at Milwaukee on Tuesday.
