The Arizona Diamondbacks have sent Trevor Bauer, their third overall selection in the 2011 draft, back to Triple-A.

Bauer, who was 7-1, 1.68 ERA, 2.72 FIP in eight Double-A starts and 4-0, 2.82 ERA, 3.33 FIP in eight Triple-A starts in 2012, didn’t fare as well for the big club. In his four starts for the D’Backs, he walked 13 batters in 16.1 innings, and recorded a 6.06 ERA, 5.15 FIP and 4.72 xFIP.

In his last outing against the Reds, he was extremely wild, walking five batters while throwing two wild pitches.
