Arizona GM Kevin Towers discusses the Diamondbacks pitching in light of the agreed upon deal with Bronson Arroyo. Prospect Archie Bradley was supposed to compete for the fifth slot in the rotation:

“I don’t want Archie to feel just because of the Arroyo signing he’s destined for Double-A or Triple-A,” Towers said. “We want it to be a very competitive spring and we want to get out of the gate early and quick.”

Bradley is very young, as he’ll play 2014 as a 21 year old. He’s only pitched 123 1/3 innings above A ball, and his walk rate is high. His strikeout and home run rates are excellent however. If it takes him a year to find his control, Arizona will be better off.

In addition, pitching staffs suffer plenty of injuries. I suspect a rotation slot will be open for Bradley at some point this year.
