But who? The Diamondbacks have as many good pitching prospects as anyone.
Well, now we know:
Corbin entered this spring behind phenoms Tyler Skaggs and Trevor Bauer on the prospect depth chart, but Corbin's out-pitched his Mobile Bay Bears teammates; in four starts, Corbin's posted a 1.67 ERA, hasn't allowed a home run, and has a solid (3.13) strikeout-to-walk ratio.
Of course, these things can also hinge on when a pitcher's scheduled to pitch again; Corbin started for the Bears last Tuesday, giving him five days of rest before starting against the Marlins on Monday. Corbin, though listed at 6'3" and 165 pounds, relies on a low-90s fastball, along with a solid slider and change-up.
Department of Corrections: When first writing about Gibson considering dropping Collmenter from the rotation, I wondered why Daniel Hudson wasn't also a candidate for demotion. Hudson was already on the Disabled List, though; he went on the DL on the 21st with a sore shoulder. I just missed it.
