PHILADELPHIA — James van Riemsdyk, Danny Briere and Simon Gagne scored in a span of 9:23 in the second period against playoff star Jaroslav Halak, and the Philadelphia Flyers routed the Montreal Canadiens 6-0 in the Eastern Conference finals opener on Sunday night.

There would be no comeback necessary this time for the surging Flyers, who rebounded from a 3-0 series hole against the Bruins and a three-goal deficit in Game 7 in Boston on Friday night. Philadelphia has won five straight overall and is 5-1 in the playoffs in front of its orange-clad crowd.

Halak was easily outplayed by Flyers fill-in goalie Michael Leighton, who is unbeaten since replacing the injured Brian Boucher in Game 5 of Philadelphia's win over Boston. Leighton made 27 saves in his first NHL postseason shutout.

Game 2 of the NHL's first final four matchup between a No. 7 and No. 8 seed, will be Tuesday night in Philadelphia.

The seventh-seeded Flyers were stunned to have home-ice advantage for the first time since the second round in 2004, and quickly made the most of it.

Defenseman Braydon Coburn scored his first NHL playoff goal during a first-period power play, van Riemsdyk pushed the lead to 2-0 just 30 seconds into the middle frame, and Briere and Gagne — on another power play — beat Halak 5:30 apart to finish the spurt.

Scott Hartnell and Claude Giroux added third-period goals against Carey Price.

Since falling behind 3-0 in the first period of Game 7 at Boston, the Flyers have outscored opponents 10-0. Leighton will take a shutout streak of 105 minutes, 50 seconds into Game 2. Not bad for a guy who sat out because of an ankle injury from March 16 until May 10.

He has allowed only four goals on 97 shots in four games since taking over for Boucher, who is likely out for the postseason with a knee injury.

Halak, the biggest factor in the eighth-seeded Canadiens' upset playoff wins against top-seeded Washington and defending Stanley Cup champion Pittsburgh, was gone 9:53 into the second after facing only 13 shots. He entered this series with an NHL-best .933 save percentage in the playoffs and a 2.42 goals-against average.

The Canadiens endured chants of "USA! USA!" and heard mocking recitals of the familiar "Ole, Ole, Ole" song that often resonates at home.

The Flyers insisted there would be no emotional or physical carry-over from their stunning win over Boston on Friday, and then they proved it.

Philadelphia had only one day off between the end of the Bruins series and the opener against Montreal. Instead of looking hung over after becoming the third NHL team to win a series it trailed 3-0, the Flyers looked as though they are still riding a wave.

The Canadiens helped the cause by taking a series of uncharacteristic undisciplined penalties — three of which directly led to goals.

Coburn started the scoring when he put in a rebound of Ville Leino's shot that bounced around in front of Halak while speedy forward Scott Gomez served a roughing penalty.

The Canadiens held a 13-6 shots advantage in the first despite not putting a puck on Leighton until 5:30 elapsed. There were two penalties called before either team recorded a shot.

The tide turned in the second period when Giroux cleanly won an offensive zone faceoff from Gomez, and nudged the puck softly toward Halak. Van Riemsdyk took two whacks at it and knocked it past Halak.

Just a second after Maxim Lapierre's penalty ended, Briere slapped a shot from the top of the right circle for his team-best eighth of the playoffs. Gagne, who has five goals and six points in five games since returning from a toe injury, made it 4-0 during another power play and ended Halak's night.
