LOS ANGELES (Reuters) –
Randy Winn belted a two-run single with the bases loaded in the 13th inning to help the San Francisco Giants beat the National League-leading Los Angeles Dodgers 7-5 on Sunday.

"I don't think this organization has had a win like that for two years," Giants' Rich Aurilia told reporters. "Maybe it will give us some momentum and propel us."

Winn also had four hits and scored four runs as the Giants won two out of three games in the series against their California rivals. He entered the game hitting .219 but went four-for-six to boost the average to .243.

"He's either scorching hot or ice cold. There's no in-between," Giants hitting coach Carney Lansford told reporters.

The defeat was the third in four games for the Dodgers since Manny Ramirez started a 50-game suspension on Thursday for testing positive for a banned drug.

"This ballclub wants to win badly," Dodgers manager Joe Torre said. "But unfortunately you have to fight your way back from disappointment."

Both teams scored runs in the 12th inning.

Winn scored on Aurilia's sacrifice fly to give the Giants the lead in the top of the inning before Casey Blake hit a solo home run to level the score at 5-5.

Winn also scored in the eighth inning off Nate Schierholtz's sacrifice fly to tie the score at 4-4.

Brian Wilson (2-0) picked up the win, pitching the final two innings for the Giants, while Guillermo Mota (2-1), who was tagged for six hits and three runs in two innings, took the loss.

Tim Lincecum, last year's National League Cy Young winner as the best pitcher, started for the Giants but lasted only six innings. He gave up six hits and four runs.
