On Saturday, San Francisco will purchase Surkamp's contract from Double-A Richmond -- where he is 10-4 with a 2.02 ERA in 23 appearances (22 starts) -- to take the hill opposite Houston starter Brett Myers. In his most recent outing last Sunday, Surkamp limited Akron two hits in eight innings. The right-hander will occupy the rotation spot belonging to Jonathan Sanchez, who remains on the disabled list with a sprained left ankle.
The Giants are coming off a 2-1 victory against the Astros on Friday, and currently trail the D-backs by three games in the division. They are feeling optimistic heading into the third game of the series, and are hopeful Surkamp will add to his track record of success.
Surkamp played for Team USA and in the Cape Cod League in 2007, was 5-2 with North Carolina State a year later, and then led the Giants' Minor League system with 169 strikeouts in 2009. He was named the California League Pitcher of the Week twice last year.
As for Myers, he is coming off a disastrous outing against Colorado in which he allowed seven runs in five innings. He's trying to snap a career-high, seven-game losing streak that has spanned two months and 11 starts. However, he still has eight quality starts in his past 13 outings.
"It was just one of those things where the ball didn't have any life on it. It was just straight," Myers said of his last start. "It could be on the corner, but it doesn't matter. If it doesn't have any angle on it, it's not going to get people out."
Astros: Mills adjusting lineup on the fly
Astros manager Brad Mills has been tinkering with his lineup a lot in the last month, which is not surprising when you consider all the new faces he's had to incorporate into the order -- center fielder Jordan Schafer, left fielder J.D. Martinez, second baseman Jose Altuve and third baseman Jimmy Paredes.
Mills sees Altuve as a two-hole hitter in the long term, but he batted him sixth on Friday against the Giants -- and hinted he could see more time there.
"Hopefully, he'll get some pitches with some guys on base, and get back to hitting balls like [we saw] the first three of four weeks he was here," Mills said.
Martinez has eight RBIs in five games against the Giants. He's batting .350 (7-for-20) with one home run.
Catcher Humberto Quintero went 2-for-3 on Friday, and has hit safely in 18 of his last 24 games.
Giants: Sandoval gets some rest
Third baseman Pablo Sandoval, who has a sore left shoulder and right foot, was given the day off on Friday but could return to the lineup on Saturday. Sandoval has also been bothered by a tight quadriceps muscle.
"He's pretty banged up," Giants manager Bruce Bochy said.
Carlos Beltran went 2-for-3 with a double on Friday. He is tied for fourth in the National League with 32 doubles.
The Giants are 33-0 this season in games in which they had a lead of three or more runs.
Including Friday's victory, the Giants are 6-4 while wearing orange jerseys this season.
Houston's Matt Downs has a Major League-best 11 pinch-hit RBIs, and is tied for first in the Major Leagues with three pinch-hit home runs.
The Astros are 3-2 against the Giants this season, and have won five of their last seven games against San Francisco dating back to last season.
