PHILADELPHIA (AP) -Given a second chance, Cole Hamels pitched like an ace when the Philadelphia Phillies couldn't afford any less.

Hamels tossed 6 1-3 sharp innings, Jimmy Rollins homered and the Phillies beat the Milwaukee Brewers 7-3 Saturday to move within two games of the NL wild-card leaders.

The Phillies can tie Milwaukee for the top spot by sweeping a day-night doubleheader on Sunday.

Philadelphia trails the NL East-leading Mets by 2 1/2 games after New York split a doubleheader against Atlanta.

Hamels (13-9) allowed two runs and six hits, rebounding from a poor outing at Shea Stadium last Sunday. Hamels had a chance to put the Phillies in a tie with the Mets, but gave up five runs in a 6-3 loss.

This time, the left-hander delivered.

''I'm more antsy after two bad starts,'' Hamels said. ''One bad start doesn't affect my morale.''

Struggling Milwaukee has lost nine of 12, including two straight in Philly. The Brewers are trying to avoid another late-season collapse. They built an 8 1/2-game lead in the NL Central by late June last year only to finish two games behind the Chicago Cubs .

''Tomorrow is big. Nothing really matters except winning,'' Brewers slugger Prince Fielder said. ''This is the way I like it. There's no pressure. Just go out there and play. This is when it's fun.''

Brewers starter Manny Parra (10-8) didn't make it out of the second inning. The left-hander gave up five runs and seven hits in 1 1-3 innings. He's 2-6 since the All-Star break.

''He hasn't pitched well,'' manager Ned Yost said. ''He pitches in spurts and doesn't contain the damage. It's been a struggle for him.''

Rollins sparked Philadelphia's inconsistent offense with leadoff hits in the first and second. He finished 3-for-5, falling a triple short of the cycle, with two RBIs and three runs.

The reigning NL MVP singled in the first and scored on Chase Utley 's double to right-center. Jayson Werth singled in Utley and Shane Victorino added an RBI single for a 3-0 lead.

Rollins doubled in the second and went to third on Utley's infield single that appeared to bounce off his foot before rolling fair. After Werth walked, Ryan Howard hit a two-run single to center for a 5-0 lead. Howard leads the majors with 131 RBIs.

''Jimmy's the catalyst. When he goes, we go,'' Howard said.

Hamels got more runs in the first two innings than in any of his losses this season. The Phillies have averaged 2.1 runs in Hamels' nine losses, including 1-0, 2-0 and 3-0 defeats.

''It's all about the team and the win, especially now,'' Hamels said.

Milwaukee sliced the deficit to 5-2 with a pair of gift-wrapped runs in the fifth. With two on and two outs, Jason Kendall lofted a fly ball to left field that was misjudged by Pat Burrell . The ball landed beyond Burrell's reach for a two-run double.

The usually cucumber-cool Hamels reacted in disgust to Burrell's gaffe, but retired pinch-hitter Angel Salome to end the inning.

Rollins hit his 11th homer, a two-run shot, off Carlos Villanueva in the sixth.

Ryan Braun connected off Chad Durbin in the eighth for his 35th home run.

''I saw some good signs offensively,'' Yost said.
