Patrick Corbin wasn't sharp in Wednesday's loss to the Rockies, allowing six runs on nine hits and two walks in six innings of work. He struck out three. That won't do, especially with Daniel Hudson edging closer to a return from the disabled list. The owner of a 5.73 ERA, 1.45 WHIP and 15/7 K/BB ratio through 22 innings, Corbin may get 1-2 more starts before being sent to the bullpen or returned to the minor leagues.
