MONTREAL (AP) -- After letting a two-game series lead slip away in the first round of the playoffs, the Philadelphia Flyers did their utmost to avoid the same fate and close out their second-round series against the Montreal Canadiens.
Scottie Upshall scored with 3:04 remaining in the third period and Philadelphia advanced to the Eastern Conference finals with a 6-4 win over Montreal on Saturday night.
"It was a great feeling," Upshall said. "A tie game with three minutes left, it's anybody's game, it's one shot, it's one bounce. [Carter] made a great shot on net. I was in the lane to see the puck and I thought I could get a stick on it and redirect it, and to get a big goal like that is pretty uplifting for your spirits."
R.J. Umberger had two goals and an assist to finish the five-game series with eight goals and one assist after he had a goal and an assist in seven games against Washington.
"Well, maybe someday I'll tell my grandkids or something like that, that would be fun," Umberger said. "I'm just going to take a moment, enjoy it but stay focused. There's plenty of time after it's over to celebrate it and enjoy it, but right now we have one thing on our minds."
Martin Biron stopped 31 shots for the Flyers, whose last appearance in the East finals was in 2004 when they lost to Tampa Bay.
The Flyers' win also ensured the first all-U.S. Stanley Cup final since 2003 and extended Canada's title drought to 15 years. Montreal was the last Canadian team to win it all in 1993.
Philadelphia finished the 2006-07 season last overall in the NHL with 56 points, the lowest total in team history.
"That's unbelievable. You don't expect something like that," Umberger said of the turnaround. "I think our team was better than where we finished last year but at the same time the guys that were here last year really focused in the summer and came into the season right, and the organization did an incredible job retooling our team and giving us a chance to compete this year."
Andrei Kostitsyn scored at 2:13 of the third to draw Montreal even at 4.
Price returned to the Montreal net after he was replaced in Game 4 by Jaroslav Halak. The 20-year-old rookie made 32 saves, including a huge left pad save to stop Daniel Briere's shot on a breakaway with 8:19 remaining.
Guillaume Latendresse drove a slap shot off the right post during a Canadiens power play before Upshall's winner.
"They took advantage of their chances," Canadiens coach Guy Carbonneau said. "This was probably the worst game that we played defensively. The other four games I thought we gave them not even 20 shots so we must have done something well in our zone, but every time they shot the puck at the net it hit something or it went into a hole that wasn't too big. They got the breaks and they took advantage of it. You've got to give them credit for that."
Philadelphia scored three times in the second, beginning with Richards' goal at 14:02 which drew the Flyers within 3-2.
Richards got credit for his fourth goal of the playoffs when he put up his left hand as Umberger's shot sailed past him and Price. A video review upheld the goal.
"I tried to catch it and luckily my hand-eye is terrible," Richards said. "It went right off my shoulder and then I turned around for the rebound and it went in the net. That was the break we needed, I think."
Umberger scored his second goal of the game at 15:44 to tie it at 3 and Hartnell's third goal of the playoffs at 17:00 gave the Flyers their first lead of the game at 4-3.
Montreal got its first lead of the series -- other than Tom Kostopoulos' overtime winner in Game 1 -- when Plekanec scored on a power play at 4:29.
Umberger tied it with a second-effort goal at 10:20 as he swiped his own rebound past Price after he shot on a 2-on-1.
Briere and Biron both went over to shake hands with Carbonneau and his coaching staff after shaking hands with the Montreal players. Briere had been booed throughout the Flyers' five games at the Bell Centre -- including two in the regular season -- after he spurned the Canadiens' free-agent contract offer to sign with Philadelphia. "It was a lot of class on his part, coming onto the ice and waiting for me to come over," Briere said. ... The Canadiens' players raised their sticks as they drew a standing ovation from the crowd following the game.
