PHILADELPHIA — Battling back from two goals down, including scoring the tying goal with 31.5 left in regulation, seemed to be the way the Bruins were setting the stage for a series-closing victory tonight.

However, the Flyers had other plans as they stayed alive with a 5-4 win in Game 4 of the Eastern Conference semifinal series at Wachovia Center.

Simon Gagne scored the game-winner with 5:20 remaining in the extra session on his first shift of OT.

After the grueling loss, the Bruins were looking on the bright side.

“It’s tough obviously, but we’ve got to recognize we got one win on the road and that’s always good,” said goaltender Tuukka Rask. “We come out from the road .500 and that’s good. We’ve got to go home and take care of the job.”

It was suggested by some of the Flyers players that now the pressure is on the Bruins, who will try to close things out against Monday night in Game 5 at TD Garden. However, the Bruins that were asked about that scenario weren’t buying what the Flyers were selling.

“Maybe they want to take the pressure off of themselves,” said Rask. “We like to play at home. Obviously it’s never easy, it’s never going to be easy, but we’ll see what happens. We don’t take the extra pressure.”

Mark Recchi, who scored two goals, including the game-tying goal, added: “Well, we’ve still got home ice, so I don’t really see it. We’ve just got to go home, play our game. This has been a great series, we knew they wouldn’t quit. We just about ended it, but you know what? We’re going back home and we’ve got two of the next three at home and we’ll be ready to play and we’ll see what happens.”

The Bruins can’t look at it as two out of three, though. They have to look at it as one and done, or they will have the pressure heaped onto them.
