SAN FRANCISCO – Ryan Vogelsong allowed one hit in seven scoreless innings and played a key role in San Francisco's go-ahead rally as the Giants beat the Oakland Athletics for the 11th straight time at home, 4-0 on Saturday.
Vogelsong (2-2) retired the first 13 batters he faced and allowed only a soft single to right-center by Seth Smith with one out in the fifth. But he was still locked in a scoreless duel with Tyson Ross before the Giants broke through for four runs with help of a disputed call in the seventh.
Buster Posey hit an RBI double and Angel Pagan added a two-run single in the big inning to help the Giants win for the sixth time in eight games. They also extended their home dominance over the A's, who have not won in San Francisco since 2008.
Emmanuel Burriss led off the seventh with an infield single between third base and shortstop. Giants manager Bruce Bochy then called back pinch-hitter Aubrey Huff from the on-deck circle to have Vogelsong try to lay down a bunt.
Tyson Ross (2-4) threw high and tight and home plate umpire James Hoye ruled Vogelsong was hit by the pitch. The A's argued that the ball hit Vogelsong's bat.
Grant Balfour came in and walked Gregor Blanco on four pitches before striking out Brandon Crawford for the first out. Melky Cabrera followed with a sacrifice fly. Posey extended the lead with a ground-rule double and Pagan's single made it 4-0.
Oakland manager Bob Melvin got ejected after arguing again with Hoye on his way to take out Balfour after Pagan's hit. Melvin was also ejected Thursday in Texas after another argument, although plate umpire Laz Diaz later apologized to Melvin after acknowledging he missed the call.
The A's rallied to beat the Rangers in 10 innings in that game, but couldn't overcome a disputed call this time to extend their longest losing streak in one stadium since dropping 12 in a row at Milwaukee from 1992-95.
The game was scoreless after six innings even though the Giants put 10 runners on base to just two for the Athletics. Ross escaped a bases-loaded, one-out jam in the first by getting Pagan to pop up and striking out Brandon Belt to end a 31-pitch inning.
He stranded two more runners in the second when he struck out Crawford. He then induced inning-ending double plays in the fifth and sixth from Cabrera and Joaquin Arias after putting runners on first and second.
Vogelsong was helped early when Cabrera made a shoestring, backhand catch in left-center to rob Jemile Weeks of a hit to lead off the game. That was the closest the A's came to a baserunner before Smith's single. Josh Donaldson, who had five RBIs on Friday night, followed by hitting into an inning-ending double play as Vogelsong faced the minimum 15 batters through five innings.
Vogelsong pitched around a leadoff walk to Daric Barton in the sixth, the only other baserunner he allowed.
NOTES: The only longer regular-season win streak over an opponent for the Giants at this ballpark came when they beat the Mets 12 straight times from 2000-03. But New York split two playoff games here in 2000. ...... Vogelsong walked in the second inning, giving Giants pitchers three walks in two games after having just two in the first 38. ... Tim Lincecum, who is 5-1 with a 1.38 ERA in seven starts against Oakland, pitches the series finale against Bartolo Colon.
