PHILADELPHIA -- Brian Wilson didn't have to wait long for a chance to protect a one-run lead.
Bengie Molina singled in the go-ahead run in the 10th inning and Wilson closed out the San Francisco Giants' 3-2 victory over the Philadelphia Phillies on Saturday night.
On Friday, the Phillies beat the Giants 6-5 on Pat Burrell's two-run homer off Wilson with two outs in the bottom of the 10th.
Burrell walked leading off against Wilson, but the hard-throwing right-hander retired the next three batters for his league-leading 10th save in 12 chances. Jack Taschner (1-0) pitched a scoreless ninth.
Never miss a local story.
"I was thinking about the situation since last night," Wilson said. "I wanted it bad. I didn't want to have to wait until (Sunday) or Tuesday. I kind of wanted a doubleheader last night."
Wilson threw all fastballs in his appearance Friday night. He started Burrell off with a slider this time.
"That was big. We wanted to be a situation where we can get him right back out there," manager Bruce Bochy said. "He settled down after the one walk."
Chase Utley hit his major league-leading 13th homer for the Phillies.
Fred Lewis had a solo homer for the Giants, who already are 7½ games behind Arizona in the NL West.
Randy Winn singled with one out in the 10th off Rudy Seanez (2-2). After Winn stole second, Molina lined a 3-1 pitch to the left-field wall to drive him in.
The Phillies finished with just three hits, none after the fifth inning.
"We just didn't hit," manager Charlie Manuel said.
Both teams got strong efforts from their starters.
Brett Myers struck out a season-best 10 over seven innings in his second-best outing since returning to Philadelphia's starting rotation. He allowed two runs and six hits.
Matt Cain gave up two runs and three hits, striking out a season-high eight in seven-plus innings, before leaving with a tight right hamstring. He's allowed three runs in his last three starts after getting tagged for nine runs against St. Louis on April 18.
Cain expects to be ready for his next start.
"I should be fine," he said.
Lewis' homer put the Giants ahead 2-1 in the fifth, but Geoff Jenkins connected on the first pitch in the bottom half to tie it.
Utley drove one the opposite way into the seats in left-center to tie it at 1 in the fourth. The second baseman with the sweet left-handed stroke is on pace to hit 68 homers, more than double his career best of 32 in 2006.
Utley, a two-time All-Star, has two more homers than the combined total of David Wright, Carlos Beltran and Carlos Delgado -- the New York Mets' 3-4-5 hitters. He's got seven more than teammate Ryan Howard, who hit 58 in 2006.
