SAN FRANCISCO -- After a disappointing 1-5 road trip, the San Francisco Giants got back on track by sweeping the lowly Houston Astros to start the second half of the season.
Buster Posey was 3-for-4 with two RBI as the Giants edged the Astros, 3-2 on Sunday afternoon.
Matt Cain (10-3) was far from perfect, but he did manage to pitch 6 1/3 innings, giving up five hits and one earned run, while walking one and striking out five. Cain won his first game since June 18 at Anaheim. That was his first start after pitching his perfect game against Houston on June 13.
Coupled with the Dodgers' loss, the Giants lead the National League West by 1.5 games.
Bud Norris (5-7) worked six innings, allowed five hits and three runs, walked six and had six strikeouts. Marwin Gonzalez had two hits and a run. The Astros have dropped 13 of 14 games and maintain the worst record in the Majors with a mark of 33-56. Houston is the only team that has not won 10 road games.
Javier Lopez started the ninth inning for the Giants and struck out Brian Bogusevic. Manager Bruce Bochy then made a pitching change for Santiago Casilla, who had blown four of his last six save opportunities. Fans voiced their displeasure twice by booing the manager when he made the move and booed again when Casilla was announced to the fans. To his credit, Casilla had an uneventful outing. He struck out Chris Johnson and Gonzalez grounded to second to end the game.
The Giants wasted no time against Norris. Gregor Blanco and Emmanuel Burriss opened with singles to left. With runners on first and second, Norris uncorked a wild pitch, advancing both runners to second and third base. Pablo Sandoval fouled out to third. Posey singled to right, scoring Blanco. Angel Pagan walked. With the bases loaded, Brandon Belt drew a walk to score Burriss, but the Giants failed to have a big inning and took a 2-0 lead.
After Cain retired the first six batters, Gonzalez doubled to right assuring the Astros would not get no-hit for a second time by Cain. Norris sacrificed to move Gonzalez to third. Jordan Schafter bunted up the first base line, and although Cain got to the ball in time, his throw was low and he was charged with a throwing error as Gonzalez scored.
The Astros tied the game in the fourth inning. Bogusevic singled to center and Johnson followed with a booming double to left-center to bring in Bogusevic. After that, Cain retired seven in a row and struck out the side in the sixth inning.
Norris had control issues again in the bottom of the fouth. He issued consecutive walks to Nate Schierholtz and Belt. He retired the next two batters but walked Blanco to load the bases. Burriss impatiently grounded out on the second pitch of the at-bat to end the inning, and the Giants had left six runners on base through four innings.
The Giants would retake the lead in the fifth. Sandoval doubled to left and scored on a single to center by Posey, his second RBI hit of the game.
