Corbin will be available out of the bullpen this weekend in Kansas City.
Zack Greinke, Taijuan Walker and Robbie Ray will start this weekend as Corbin gets acclimated to a bullpen role in preparation for the postseason. Corbin has endured a couple rough starts lately, but he went on a great run in July and August, reestablishing himself as a viable major-league starter after a disastrous 2016 season.
