Corbin allowed one hit and struck out six over four scoreless innings as the Diamondbacks edged the Giants, 4-3, in a Cactus League game at Scottsdale, Ariz.
The D-backs' No. 8 prospect retired seven straight batters at one point and ended up walking two. Corbin, who did not figure in the decision, ran into some trouble in the sixth after allowing a leadoff single to Aubrey Huff and walking Ryan Theriot with one out. But the 22-year-old left-hander struck out Brandon Crawford and Brett Pill to end the threat.
Corbin has been lights-out in Spring Training. The 2009 second-round pick lowered his ERA to 0.84 and has allowed only seven hits over 10 2/3 innings in four Cactus League outings.
Bauer, MLB.com's No. 9 overall prospect, got the start and gave up two runs on six hits over three innings. The third pick in last year's Draft has a 3.60 ERA this spring.
Former first-round pick A.J. Pollock, the D-backs' No. 6 prospect who entered in the seventh, ended the game with his first Cactus League homer.
