Giants walk off in extras

Aug 28, 2011 - 6:26 AM San Francisco, CA (Sports Network) - Jeff Keppinger singled home Mark DeRosa with two outs in the bottom of the 10th inning Saturday to lift the Giants to a 2-1 win over the Astros.

DeRosa singled with one out against Fernando Rodriguez (2-3) and swiped second for his first stolen base since 2009. Two batters later, Keppinger lined a 94 mph fastball into shallow right field and DeRosa beat Brian Bogusevic's throw for the winning run.

"I guess I tip my hat to him," Rodriguez said of Keppinger. "He's just one of those guys that you gotta battle and hope he's the one that makes a mistake."

The Giants have won the last two games of this four-game series after dropping the opener. They remained three games behind Arizona in the NL West after the division-leading Diamondbacks beat San Diego.

Jeremy Affeldt (3-2) faced only one batter but got the final two outs on a double play in the top of the 10th to earn the win.

The Giants scratched out their first run hours earlier when Mike Fontenot doubled to lead off the bottom of the first inning, went to third on Keppinger's ground out and scored on Carlos Beltran's grounder.

The Astros tied the game in the fifth on Carlos Lee's double, which scored Jason Bourgeois after a leadoff single.

Earlier Saturday, the Giants placed outfielder Nate Schierholtz on the 15-day disabled list due to a fracture in his right foot.

Eric Surkamp came up from Double-A Richmond to make his major league debut and pitched great, giving up six hits and three walks with four strikeouts for San Francisco.

"The kid showed great poise out there," said Giants manager Bruce Bochy. "He got in a couple jams, and he showed pretty much what I'd heard: good stuff, good poise. I just thought he had a great debut."

Brett Myers went seven innings for the Astros, giving up just two hits and three walks while striking out seven.

Game Notes
