Bryan Augenstein

Augenstein hit the ground running with a 5-0 start at Double-A Mobile before getting a surprise early-season callup to Arizona when the big league rotation was scrambling to get by following the loss of Brandon Webb. He made a pair of starts with the D-Backs before getting sent down to Triple-A Reno, where a case of elbow inflammation limited his workload. Augenstein isn't overpowering, but he's shown good command throughout his stops in the minors and he's shown an aptitude for generating outs on the ground. In the worst-case scenario, he looks like a viable relief option for the D-Backs going forward, but Augenstein may be able to contribute in the back of the Arizona rotation as the team's fifth starter if his secondary stuff and command are good enough for him to get big league hitters out consistently.
