After starting the season in a downright dreadful fashion, the Yankees’ bullpen has righted itself and become a legitimate weapon. Most of the credit goes to the arrival of Al Aceves and the awesomeness of Phil Hughes, and rightly so, but they’re not alone in the bullpen’s revival. Since the start of June, David Robertson has pitched in 25 games for the Yanks, striking out 37 batters in 26 innings, contributing to his AL-best 12.69 K/9. Opponents are hitting just .204 off him in that time, and his groundball-flyball ratio is a studly 1.90. Sure, Robertson’s 5.13 BB/9 is too high, but he’s walked just four batters in his last 12 innings, so he’s improving. He’s also added velocity throughout the season.
Robertson absolutely annihilated the minors after signing for $200,000 out of The University of Alabama as a 17th round pick in 2006, and it looks like he’s starting to get over that rookie hump. As far as non-setup middle relievers go, it doesn’t get much better than David Robertson right now.
