According to Carl Steward of the San Jose Mercury News, the Giants will call up prospect left-hander Eric Surkamp to make his major league debut tonight against the Astros.
Jonathan Sanchez and Barry Zito are both sidelined with ankle sprains and Dan Runzler gave up four runs on three hits and three walks over 1 2/3 innings in his first major league start last Sunday against the Astros, so Surkamp will be asked to serve as the fifth starter for the time being.
Surkamp, 24, has improved his stock this season by posting a 2.02 ERA and 165/44 K/BB ratio over 142 1/3 innings with Double-A Richmond. He has averaged 10.7 K/9 and 2.5 BB/9 over parts of four seasons in the minor leagues. The 2008 sixth-round pick isn’t a hard thrower, but his changeup and curveball are considered plus-pitches.
