There was a strange, almost-foreign sound Tuesday night that echoed around the Wells Fargo Center after a Flyers power play ended late in the first period.

Cheers. Loud, throaty cheers.

Claude Giroux's power-play goal triggered the fans' early outburst, and late goals by Kimmo Timonen and Wayne Simmonds keyed a 5-2 victory over the Ottawa Senators.

Timonen (three points) and Simmonds scored 23 seconds apart as the Flyers snapped a 2-2 tie and took a 4-2 lead with 8 minutes, 7 seconds remaining. The goals were scored shortly after a video review denied a goal that would have given the Senators a 3-2 lead.

The Flyers have points in five straight games (4-0-1), lifting their record to 8-10-2. They are 8-7-2 since coach Craig Berube replaced Peter Laviolette.

With the score tied at 2-2 midway through the third period and Flyers goalie Steve Mason out of position, Kyle Turris appeared to have an open net out front, but defenseman Nick Grossmann blocked his shot with his left skate to keep the game tied.

Part of the puck appeared to cross the goal line. After a lengthy video review, the no-goal call on the ice was upheld.

Adam Hall ended the scoring with an empty-net goal.

The Senators had tied it at 2-2 as Turris scored on a rebound, backhanding the puck into the net on a power play with 16:48 left in the third period.

The Flyers' mostly anemic power play has produced more boos than goals at home games this season. Before Giroux scored, they were 3 for 41 (7.3 percent) on the power play at the Wells Fargo Center, placing them next-to-last in the NHL in home games.

After taking a slick right-circle pass from Jake Voracek, Giroux's left-circle shot went past sprawling goalie Robin Lehner with 2:16 left in the opening period to give the Flyers a 1-0 lead.

A little over five minutes into the second period, the Flyers got a gift and made it 2-0 on Sean Couturier's first goal of the season. Couturier, who missed a wide-open net on a first-period rebound, shot the puck from behind the goal line near the boards and somehow beat Lehner to the short side.

"It felt good to finally get one," Couturier said. "I got a lucky bounce and I'll take it."

Couturier, whose team is now 4-7 at home, said the goal lifted a weight off his shoulders.

"I feel 20 pounds lighter," he cracked.
