PHILADELPHIA -- Ryan Howard took a mighty cut, dropped his bat and admired the shot.
The big slugger didn't go down looking in a clutch spot this time, and Roy Halladay overcame a shaky start to help the Philadelphia Phillies beat the St. Louis Cardinals 11-6 Saturday night in the opener of their NL division series.
Howard shook off his season-ending strikeout last October to hit a go-ahead, three-run homer in a five-run sixth inning, sending Citizens Bank Park into a frenzy. Halladay retired his last 21 batters, and the NL East champions began their all-or-nothing postseason run with a comeback win.
Halladay allowed three runs and three hits, striking out eight in eight innings. He didn't allow a runner after Skip Schumaker led off the second with a single.
Game 2 is Sunday night, with Cliff Lee pitching for Philadelphia against Chris Carpenter, who is starting on three days' rest.
Raul Ibanez hit a two-run shot off Kyle Lohse to cap the Phillies' burst in the sixth, and Shane Victorino had three hits and two RBIs.
Last year, in his first career playoff start, Halladay threw the second no-hitter in postseason history in Philadelphia's 4-0 victory over Cincinnati.
His bid for an encore didn't last one batter, and Lance Berkman hit the first three-run homer off Halladay in three years to put the wild-card Cardinals up 3-0 in the first.
But the offense bailed out Doc.
Lohse retired the first 10 batters before Chase Utley hit a double off the right-field fence in the fourth. The righty, who was 14-8 this season, ran out of gas in the sixth.
Down 3-1, Jimmy Rollins singled to start the inning. After Utley struck out, Hunter Pence grounded a single up the middle. That brought up Howard, who heard a lot of criticism last year for taking a called third strike with the tying run on second base to end the Phillies' season against San Francisco in the NL championship series.
Howard worked a full count before launching a towering drive into the second deck in right-center to give the Phillies a 4-3 lead.
The towel-waving crowd went wild, and Howard came out for a curtain call.
Victorino followed with a single. Ibanez then lined a two-run homer to right to end Lohse's night.
Lohse allowed six runs -- five earned -- and seven hits in 5 1-3 innings.
The Cardinals scored three times in the ninth off relievers Michael Stutes and Ryan Madson, highlighted by Schumaker's two-run double.
The two teams took different roads to get here.
The Phillies cruised to their fifth straight division title, winning a franchise-record and major league-best 102 games. Anything less than a second World Series title in four years will be considered a failure by players, management and fans.
The Cardinals needed an incredible collapse by Atlanta and help from Philadelphia to earn the wild card. St. Louis trailed the Braves by 10½ games on Aug. 25, but went 23-8 the rest of the way and got in after Game 162 when the Phillies completed a three-game sweep in Atlanta.
For a while, it seemed the Phillies might regret helping the Cardinals reach the playoffs.
A day after borrowing a line from William Shakespeare, saying he "came here to bury Caesar, not praise him," Halladay didn't back up his words right away.
Rafael Furcal led off the game with a single and stole second. One out later, Halladay walked Albert Pujols on four pitches. Berkman drove the next pitch off the mini-scoreboard hanging on the facing off the second deck in right field.
The switch-hitting Berkman hit all 31 of his homers in the regular season from the left side. No. 32 was the first three-run homer Halladay allowed since Aug. 21, 2008, when Hideki Matsui connected for the Yankees in a 14-3 loss to Toronto.
The Phillies will turn Berkman around the next two games with lefties Lee and Cole Hamels on the mound.
Howard hit a sacrifice fly in the seventh, and Victorino and Ibanez each had RBI singles in the inning to pad Philadelphia's lead.
An unearned run got Philadelphia within 3-1 in the fourth. After Utley's one-out double, Pence struck out and Howard walked. Victorino hit a foul pop down the left-field line that should've ended the inning.
But third baseman David Freese tried to make an over-the-shoulder catch and the ball fell out of his glove for an error. Victorino hit an opposite-field single to left to score Utley.
Halladay, a two-time Cy Young Award winner who won it last year in his first season in the NL, was 19-6 with a career-best 2.35 ERA and eight complete games this season.
He made certain the relievers stayed in the bullpen until this game was out of reach.
A crowd of 46,480 was the 218th straight sellout at Citizens Bank Park, including postseason play. The stadium resembled an apple orchard with all the red-clad fans.
NOTES: Cardinals RHP Kyle McClellan was disappointed that he was left off the roster because of a tired arm. "McClellan is a real weapon," manager Tony La Russa said. "That was a very tough call, and I know he's very upset with it, and he should be. Made totally on his best interest."... Only the New York Yankees (27) have won more World Series titles than the Cardinals (10). ... The Cardinals were 6-3 vs. the Phillies in the regular season. ... The Phillies are 15-7 in Game 1s, while the Cardinals fell to 16-19. ... The Cardinals didn't have five-time All-Star, LF Matt Holliday because of a hand injury. ... Howard is 9 for 18 with three homers off Lohse. ... The Phillies, who acquired Pence from Houston on July 29, are now 8-0 with all of their regulars in the lineup. ... Pence was 2 for 5 with two RBIs and two runs in his first postseason game.
