PHILADELPHIA -- The Philadelphia Flyers considered Wednesday's clash with the Boston Bruins a must-win on home ice.

And by the look of their third-period push, they truly believed it.

Trailing 2-1 midway through the final stanza, the Flyers ambushed the Bruins for an important come-from-behind 3-2 win at Wells Fargo Center.

"Huge win for us," Flyers defenseman Mark Streit said. "We just keep playing and we don't lose faith."

Philadelphia (19-15-7) scored a pair of goals in a span of 1 minute, 22 seconds in the third to win its fourth straight and tie its season-best winning streak.

Right winger Wayne Simmonds netted the tying goal while Streit came through with the game-winner, helping the Flyers gain valuable ground in the standings as they now trail the Bruins and New Jersey Devils by two points for the Eastern Conference's second and final wild-card spot just over half-way through the regular season.

"This time of year, you want to be in position to make a push," Flyers center Claude Giroux, who finished with three assists, said. "It's all about confidence. Right now we have it and we have to make sure we keep it."

Boston (21-16-5) is having a tough time finding any confidence as it's lost three in a row and eight of its last 10. Coming into the game, the Bruins were 14-3-1 when leading after two periods of play.

"Right now, it's a frustrating time for our team," Bruins coach Claude Julien said. "Missed opportunities at one end and mistakes at the other, so we've got to turn the tide."

Both the game-tying and go-ahead goals came on rebounds as Philadelphia's second-effort chances burned Boston.

"We played a pretty good game," Bruins goalie Tuukka Rask said. "I don't want to overanalyze things, but from my perspective, a goaltender's perspective, it's just a couple unlucky bounces."

Simmonds outskated two Bruins up ice to tie the game 2-2 at 10:10 of the third period. On a breakout, right winger Jakub Voracek found Simmonds, who scored his 11th of the season on a rebound off his initial shot, which bounced right back to him.

Streit then won it shortly after with his fourth goal of the season. Voracek was huge, scoring a goal to go with two assists.

"Not overly worried about our defensive game," Rask said. "Just some tough bounces against me and us as a team. Those seemed to decide the game. Just have to stay even-keeled and stick with it."

Rask (14-13-4), who came in 9-1-2 with a 929 save percentage and 2.07 goals-against lifetime against Philadelphia, made 18 saves.

Flyers goalie Steve Mason (10-10-5) won his third straight by stopping 30 shots.

"It was kind of a must-win for us," Mason said. "Here's a team that's in front of you. You need to get these points.

"Guys worked hard for some greasy goals."

After a lousy power play expired, Philadelphia quickly made up for it by netting the game's first goal with 2:32 remaining in the opening period. Giroux whipped a shot on net and Voracek impressively corralled the rebound, reached around a defenseman and put it home for a 1-0 lead.

The Bruins drew even 8:38 into the second when center Max Talbot spotted defenseman Kevan Miller cross-ice and delivered him a pass with plenty of time to windup and blast a snap shot top shelf past Mason.

As Philadelphia came up empty on its first three power plays, Boston needed just one to grab the lead in the second. The Bruins, who entered with the NHL's most successful man advantage, jumped ahead 2-1 when right winger Loui Eriksson scored on a rebound attempt just 25 seconds into their two-minute power play.

The marker, which came with 3:34 left in the second period, was Eriksson's 15th of the season and Boston seemed in control at second intermission.

But the Flyers wanted this one and showed it late.

"Every two points is real important for us," Flyers coach Dave Hakstol said. "We felt that way coming into this game."
