Surkamp made his most recent start last Thursday and will have received his regular four days of rest by Tuesday. By contrast, left-hander Mike Kickham, another candidate to get the start, pitched Saturday night and wouldn't have enough recovery time to face the Reds.
Surkamp, rated the No. 9 prospect within the organization by MLB.com, has progressed steadily since undergoing Tommy John elbow surgery last July 24. He's 2-0 with a 4.00 ERA in nine starts this year with Class A San Jose and Fresno. With Fresno only, Surkamp's 2-0 with a 4.79 ERA, a 1.65 WHIP (walks plus hits per inning pitched) and a .316 opponents' batting average in four starts.
Surkamp was a long-shot candidate for a spot in the Giants' starting rotation last year before his elbow problems materialized. He made six late-season starts for San Francisco in 2011, posting a 2-2 record and a 5.74 ERA.
A Cincinnati native, Surkamp would face his hometown team for the first time.
