SAN FRANCISCO -- Brett Myers can't remember back to his Little League days but he's pretty sure he never had to close a game before Thursday night.
Myers made his first big league save look easy. He pitched the ninth in place of the injured Tom Gordon, retiring all three batters he faced for what is most likely his first save at any level.
"I was pretty much ready to go," Myers said. "I played catch with the outfielder twice and it was nothing unusual. It's still getting people out."
Shane Victorino and Chase Utley each drove in two runs for the Phillies, who beat San Francisco for the 11th time in their last 13 meetings.
"We got big hits and I like the way we hit early," Phillies' manager Charlie Manuel said. "I also liked the way we hung in there at the end. (Myers) is going to be good., He has the ability and the stuff. He just needs to calm down and control his adrenaline. He was in a hurry to get in there."
Giants starter Matt Cain, who entered the game with the NL's third-best ERA (1.54), didn't make it out of the fourth inning and the Giants lost for the fifth time in seven games.
"I felt good coming out of the bullpen," Cain said. "I just got behind a lot of guys. I got to them when they had good hitting counts and they took advantage."
Rollins, a native of Oakland, provided a rare show for his local fans. The shortstop, tied with Barry Bonds with nine home runs this season, entered the game with a career .188 average and one triple in San Francisco.
After striking out in his first at-bat, Rollins put the Phillies on the board with a two-run triple in the second that hit off the center-field fence and sparked a four-run rally. He led off the fourth with a triple that hit halfway up the right-field screen and started a five-run outburst.
"That's what makes him so good," said Victorino, who left the game early with tightness in his back. "He comes up and gets the two-run triple and gets himself into scoring position. He makes it easy for the rest of us."
Eaton (3-2) allowed six runs and eight hits over five-plus innings but still managed to beat the Giants for the first time since June 7, 2001, when he was with San Diego. He was 0-4 in 10 starts against San Francisco until Thursday.
Eaton walked three and struck out five.
"He had a tough six innings," Manuel said. "He has the stuff but he has trouble getting out of jams. I think the biggest problem is for him to make a few more quality pitches."
Cain (1-2) lasted three-plus innings, the shortest start of his career. He allowed seven earned runs, matching his career high, eight hits and four walks.
Cain's ERA rose to 3.08 after he allowed more runs Thursday than in his previous five starts combined.
Pat Burrell, Abraham Nunez and Carlos Ruiz also drove in runs for the Phillies.
The Giants had all but conceded the game, replacing Bonds, Rich Aurilia and Bengie Molina after five innings. Their replacements helped make it interesting with a five-run sixth against Eaton and Ryan Madsen.
Omar Vizquel delivered a two-run double and Randy Winn doubled in a run while backup catcher Eliezer Alfonzo tripled in a run and backup infielder Kevin Frandsen, recalled from the minors earlier Thursday, drove in a run.
Madsen got five outs and Antonio Alfonseca recorded four outs to get to Myers.
Vizquel batted in the eighth spot, the first time he hasn't batted first or second since June 14, 2001, when he hit eighth for Cleveland. ... Burrell broke an 0-for-19 streak with his fourth-inning double. ... Phillies 1B Ryan Howard took over the major league lead with his 27th walk. ... Phillies OF Aaron Rowand reached base safely for the 24th consecutive game.
