Patrick Corbin blanked Cincinnati on two hits through six innings, strengthening his bid for a spot in Arizona's rotation in the Diamondbacks' 2-1 loss to the Cincinnati Reds on Friday night.
The left-hander, competing with Randall Delgado to be Arizona's No. 5 starter, struck out seven and walked two.
Bronson Arroyo, whose previous outing ended when he was struck in his pitching hand by a line drive, gave up a run on Jason Kubel's homer, scattering seven hits with one strikeout in six innings.
Ryan Ludwick got both hits off Corbin, a first-inning single and a fourth-inning double. Kubel, batting .150 for the spring going into the game, hit his second home run of the preseason.
