Home dominance continues to be the theme in the Bay Bridge Series.
Tim Lincecum has thrown some gems in this rivalry, including a 3-0 mark at AT&T Park.
He'll look to win for the first time in four starts Sunday and lead the San Francisco Giants to their 12th straight home victory over the Oakland Athletics.
San Francisco (21-19) has taken the first two games of this series, marking 14 straight wins for the home team in this rivalry. Oakland (20-21) hasn't won across the bay since a 5-3 victory June 15, 2008.
Lincecum (2-3, 5.77 ERA) began the Athletics' losing streak in AT&T Park with a seven-hitter in a 3-0 victory three years ago. He's 5-1 with a 1.38 ERA with 54 strikeouts over 52 1-3 innings in seven career starts against Oakland, winning the last three at home with two complete games.
The Oakland hitter who has faced him the most is Seth Smith, who is 8 for 28 with three homers. That longball total matches Arizona's Paul Goldschmidt and Philadelphia's Ryan Howard for the most against Lincecum.
The two-time NL Cy Young Award winner has pitched poorly for most of this season, and enters after he did not get a decision as he gave up four runs over seven innings Tuesday in a 5-4 loss to Colorado. The Giants have won two of the right-hander's eight starts.
"I'm going to take the positives that I had from the last couple of games and just put it all together, and all together hopefully the outcome is better," Lincecum told the Giants' official website.
Lincecum has a tough act to follow after Ryan Vogelsong gave up one hit over seven innings and two relievers finished up with hitless innings in Saturday's 4-0 victory. Vogelsong retired the first 13 batters he faced and allowed only a soft single by Smith with one out in the fifth.
The Giants scored all their runs in the seventh inning. Melky Cabrera had a sacrifice fly, Buster Posey extended the lead with a two-out RBI double and Angel Pagan - 17 for 37 during a 10-game hit streak - added a two-run single.
"You have to capitalize on it,'' Posey said. "We were able to do that.''
Josh Donaldson went 0 for 3 for Oakland one day after he had three hits and five RBIs in Friday's 8-6 loss.
Manager Bob Melvin was ejected for the second time in three days, and wasn't happy that the Giants stretched the lead with two outs.
"At some point you have to move on and continue to play and try to shut it down,'' Melvin said. "We tried to. They just ended up scoring some runs right there.''
The A's are trying to avoid their longest losing streak in one stadium since dropping 12 straight in Milwaukee from 1992-95.
Sunday starter Bartolo Colon (3-4, 4.13) has lost his last two outings for Oakland. He gave up four runs and a season-high 12 hits in Tuesday's 4-0 loss to the Angels, falling to 2-1 with a 2.31 ERA in five road starts.
The veteran right-hander's two career outings against the Giants came between 2002-03. He went 1-1 with a 5.65 ERA.
