BOSTON - Down 3-0 in the series, then down 3-0 in Game 7. It looked as if the Philadelphia Flyers had finally run out of rallies against the Boston Bruins.
Turns out Simon Gagne and his teammates were just warming up.
Taking advantage of a too-many-men-on-the-ice call, Gagne scored on a power play with 7:08 left for 4-3 victory Friday night to win the Eastern Conference semifinals.
"All the adversity we had fought through ... it's absolutely incredible," said Philadelphia's Scott Hartnell.
The win set up a most unlikely matchup for a trip to the Stanley Cup final—the seventh-seeded Flyers versus the eighth-seeded Montreal Canadiens.
The Bruins became the third team in NHL history to lose a series after winning the first three games.
"We got a little carried away from our game plan and lost our composure," Bruins captain Zdeno Chara said.
The Flyers capitalized when captain Mike Richards' shot from the right circle hit players in front of Tuukka Rask. The puck bounced and Gagne, stationed to Rask's left, flipped the puck over the goalie's right shoulder.
Gagne, a major force since returning from a toe injury for Game 4, scored with 18 seconds left in the power play.
"I saw two centremen out there and I said, 'What's going on,'" said Milan Lucic, who had two goals for Boston. "I knew there was a miscommunication out there and we got caught."
The only other teams to win a series after trailing 3-0 were the 1942 Toronto Maple Leafs, who beat Detroit, and the 1975 New York Islanders, who eliminated Pittsburgh. The other 159 teams that won the first three games in a series all won them.
The Bruins shot out to a 3-0 lead on power-play goals by Michael Ryder and Lucic and another goal by Lucic. And only 14:10 had been played. Then James van Riemsdyk scored with 2:48 left in the first period for the Flyers.
"It feels nice to finally get one after I don't know how many games it's been," van Riemsdyk said.
Second-period goals by Hartnell at 2:49 and Danny Briere at 8:39 tied it at 3.
When the final buzzer sounded, the Flyers poured off their bench and surrounded goaltender Michael Leighton, who started his second playoff game for injured Brian Boucher.
While the Flyers celebrated, the yellow towels that fans twirled to spur on their team floated to the ice, no longer needed until next season. Boston centre Patrice Bergeron took a slap shot with one of them—like the Bruins, it didn't go far.
Boston was hurt by the same too-many-men-on-the-ice call in the 1979 Stanley Cup semifinals against Montreal. In that Game 7, the penalty led to Guy Lafleur's tying goal with 74 seconds left in the third period, then Yvon Lambert won it in overtime for the Canadiens.
"When that final buzzer went, it was a sigh of relief," Richards said.
The Flyers will host Montreal in Game 1 on Sunday night.
Boston lost its third straight Game 7 and first since falling to Carolina in last year's conference semifinals after battling back from a 3-1 series deficit.
The Bruins and Flyers played aggressively at the start with plenty of end-to-end action in the first five minutes.
Boston got a break when Hartnell was penalized for high-sticking at 5:19 and Ryder scored his fourth playoff goal on a rebound eight seconds later. Another Bruins power play three minutes later led to another goal, this one by Lucic, who tipped in a pass across the crease from Dennis Wideman in the right corner.
Lucic struck again, scoring his fifth playoff goal five minutes later, at 14:10 on a shot from the right circle.
Leighton, who took over in Game 5 after sitting out nearly two months, didn't let another goal past him.
Van Riemsdyk began the comeback with his first playoff goal three minutes after Lucic's second goal on a soft shot that trickled by Rask. That was the first of nine consecutive shots by Philadelphia. One of them was Hartnell's second goal of the playoffs. Another was Briere's seventh playoff goal—on a wraparound.
NOTES: Patriots coach Bill Belichick attended the game. ... Philadelphia beat second-seeded New Jersey in the first round, while Boston eliminated third-seeded Buffalo. ... The Flyers are 8-6 in seventh games. The Bruins are 9-10.
