The fourth overall pick in the draft, righthander Trevor Bauer was overshadowed by rotation mate Gerrit Cole while at UCLA, but after turning pro he became one of the most impressive young arms anywhere in the minors. After blowing past high-A ball last year, he found his level in AA, and that's where he should open 2012. Bauer is a smallish pitcher, with a bit of an unconventional motion, but he's not the overpowering Lincecum type, more of a bag-of-tricks pitcher with a good head for the game. While he can dial his fastball up to 96mph when he wants to, he's much more effective when he holds back and lets the natural movement of his breaking balls do the work for him. It's possible he breaks camp with the Diamondbacks, but with the team not hurting for starters just yet, it's most likely that his real prime time won't be until 2013.
