PHILADELPHIA -- Brett Connolly wore a hat that read, "Trust In Boston."

That has been hard to do when the Boston Bruins have held third-period leads against the Philadelphia Flyers this season.

But on Monday at Wells Fargo Center, Connolly and the Bruins refused to let this one slip away as the right winger netted a game-winning goal with 1:54 left in regulation to stave off the Flyers for a 3-2 victory.

"We knew it was going to be tough," Connolly said. "They're good in this building, we knew they were going to come."

In two games this season Philadelphia came back from third-period deficits for a pair of wins over Boston.

Not this time.

The Bruins (26-17-5) have won five of their last six games since falling to the Flyers on Jan. 13 and hold an Eastern Conference playoff spot in third place of the Atlantic Division with one game remaining before the All-Star break.

"When you're ahead of teams, you have to keep those points for yourself," Boston center Patrice Bergeron said. "We gave (Philadelphia) four points, so it's one of those where we wanted to get that win in regulation."

The Flyers (20-18-8) have dropped three in a row and four of five since that victory on Jan. 13, slipping to seventh place in the Metropolitan Division.

With Philadelphia trailing 2-0, right winger Wayne Simmonds scored two goals to tie it -- one in the second period, the other in the third at 12:08. The Flyers have five wins when trailing after two periods, but couldn't get their sixth.

"It's fun when you win, not when you lose," Simmonds said of comebacks. "So that wasn't too much fun."

Bruins goaltender Tuukka Rask (17-14-4) was strong, making 34 saves and improving to 10-2-2 lifetime against the Flyers.

Connolly, who had just one goal since Dec. 2 and was a healthy scratch last game, gave Rask a win and himself a confidence boost.

"Obviously it's been a frustrating little while," Connolly said. "I've been getting lots of chances and good opportunities, so to see that one go in in such a big game right before the All-Star break, it's good."

Philadelphia goaltender Michal Neuvirth (10-6-2) played in just his second game since Jan. 5 and stopped 28 shots. His team fell behind with a lackluster and undisciplined first period.

"This time of year you can't play 40 minutes," Flyers defenseman Michael Del Zotto said. "We had a tough start. We've talked about how we have to play a full 60 minutes if we want to be successful, especially against these teams we're playing here. We're playing for every point."

Boston used its second-ranked power play to jump on Philadelphia in the first period.

It took just 5:04 for the Bruins to strike first when centers Ryan Spooner and Bergeron got into the slot and connected for a 1-0 lead on the man advantage. Spooner delivered a short pass to Bergeron, who simply guided the puck past a recovering Neuvirth.

It was Bergeron's 19th goal and Spooner's 26th assist.

With 2:33 left in the opening period, the Bruins went on the power play again and capitalized as left winger Brad Marchand went top shelf from one knee to supply Boston a 2-0 cushion.

Defenseman Zdeno Chara facilitated Marchand's fifth goal in as many games by slicing the Philadelphia defense with a cross-ice pass.

"We're kind of shooting ourselves in the foot the first period," Del Zotto said. "It haunted us tonight."

After a big first period, the Bruins shot themselves in the foot during the second by committing four penalties. However, Boston withstood Philadelphia's persistent attack, killing off three of the four power plays despite being outshot 15-6 over the stanza.

"It was a tough 10 minutes for us," Rask said. "But we battled through, battled hard and kept them at one goal."

Simmonds scored after he got the puck from center Brayden Schenn, who impressively fed him across the goal crease to bring Philadelphia within one.

The Flyers then made their third-period push as Simmonds scored the equalizer.

"We didn't let that deter us from what we wanted to do and that was win the game," Bruins coach Claude Julien said.

Boston still trusted itself.

"We have enough guys that can send the right message there on the bench," Julien said. "And they did."
