Chafin pitched 7.1 innings this spring, posting a 3.68 ERA along with a 0.82 WHIP and a 10:1 K:BB.
After posting a 2.76 ERA and 1.15 WHIP in 75 innings out of Arizona's bullpen last year, Chafin will again serve in a middle-relief role this season. The 2011 sandwich-round pick showed an intriguing ability to miss bats this spring, and if that translates into an improvement over last year's 58:30 K:BB, he could end up seeing some save chances down the road.
