Corbin, who will make his season debut today against the Rockies, plans on incorporating his changeup more, Nick Piecoro of the Arizona Republic reports.
In his breakout 2013 season, Corbin relied almost entirely on a fastball-slider combo. The 27-year-old lefty said he wants to use his changeup more this season against both righty and lefty hitters, and an opposing scout said the pitch "was a lot better this spring."
