PHILADELPHIA — Cole Hamels was so dominant the Milwaukee Brewers were glad to see Brad Lidge come in. The switch to their perfect closer nearly cost the Philadelphia Phillies.

Behind their top two arms, the Phillies grabbed their first postseason victory in 15 years — barely.

Hamels pitched eight brilliant innings, Lidge escaped a ninth-inning jam and Philadelphia took advantage of Mike Cameron's miscue in center field for a 3-1 win over Milwaukee in their NL playoff opener yesterday.

Chase Utley's two-run double slipped out of Cameron's glove in the third, helping the Phillies take a 3-0 lead. Lidge allowed a run in the ninth but struck out Corey Hart with runners at second and third to end it.

"I can't let him get a hit there," said Lidge, who was 41-for-41 in save chances this season. "I've always been a strikeout pitcher and that's what I wanted to do."

Game 2 in the best-of-five series is today, with ace CC Sabathia going to the mound for the wild-card Brewers on three days' rest for the fourth consecutive start. Brett Myers pitches for the Phillies.

It'll be tough for anyone to match Hamels' superb performance. The 24-year-old lefty retired the first 14 batters and allowed two hits, striking out nine.

Phillies manager Charlie Manuel considered sending Hamels out to start the ninth, but decided to go with Lidge. The Brewers got the tying run to the plate, but Prince Fielder fanned for the second out. After J.J. Hardy walked to put two runners on, they advanced on a wild pitch. Then Hart struck out swinging to end it.

"Not too many times you can say you're happy to see Lidge, but we didn't hit the ball hard off Hamels all day," Brewers manager Dale Sveum said.

Hamels baffled the fastball-hitting Brewers with his dazzling changeup, helping the Phillies earn their first postseason win since the 1993 World Series against Toronto.

The NL East champions were swept out of the first round by the surging Colorado Rockies last year. Hamels lost the opener of that series.

Making his second start since returning from surgery for a torn knee ligament, Milwaukee's Yovani Gallardo got rattled after his defense fell apart in the third.

The 22-year-old righty allowed three unearned runs and three hits in four innings, walking five. Gallardo became the second pitcher in major league history to start a postseason game without recording a win that year. He pitched in three games before he injured his right knee on May 1 and had a 1.88 ERA to go with four no-decisions.

Carlos Ruiz started Philadelphia's third inning with a single. Hamels then bunted hard to third baseman Bill Hall, who bobbled the ball, costing him a chance to get Ruiz at second. Second baseman Rickie Weeks dropped Hall's throw to first for an error.

Gallardo almost worked out of the jam, though. He retired Jimmy Rollins on a shallow fly and struck out Jayson Werth. But Utley ripped a liner through a swirling wind to center. Cameron raced back and reached up only to have the ball bounce out of his glove.

Both runners scored on Utley's double for a 2-0 lead. A three-time Gold Glove winner, Cameron usually makes that play look routine.

"If he doesn't make that catch, nobody can," Sveum said.

Gallardo intentionally walked Ryan Howard and walked Pat Burrell to load the bases. Gallardo walked Maui's Shane Victorino to force in another run, before retiring Pedro Feliz on a fly to center.
