PHILADELPHIA — Claude Giroux scored 1:59 into overtime and the Philadelphia Flyers scored three straight goals in the rain to beat the Pittsburgh Penguins 4-3 on a soggy Saturday night at Lincoln Financial Field.

The Flyers and Penguins took one of the NHL's more heated rivalries outdoors and into prime time as part of the Stadium Series showcase. The rink that stretched from 30-yard line to 30-yard line needed a squeegee more than a Zamboni, but nearly 70,000 fans stuck around the home of the Eagles to watch the Flyers play the marquee game on their schedule.

The Flyers gave them a win to remember.

With rain pounding the ice in third period, the Flyers got going. James van Riemsdyk, playing in his record sixth outdoor game, made it 3-2 on a power-play goal with 3:04 left. Jake Voracek tied it at 3-all with 19.7 seconds left, sending what was left of the sellout crowd into a frenzy.

Giroux, the Flyers' All-Star captain, made sure the game didn't last much longer. He slipped the winner past Matt Murray, and the Flyers celebrated in the mist. Giroux said he felt “goosebumps” scoring in the clutch in his 800th career game.

“I was able to get a step on their D and squeak in my goal,” Giroux said.

Giroux capped a stunning comeback in what has mostly been a season to forget for the Flyers.

Gritty, the Flyers wildly popular rookie mascot, zip lined in a glow-in-the-dark jersey from the top of the Linc to kick off the party, and later was caught streaking as he scurried away from “security” in a mad scamper toward the tunnel.

As usual, Gritty was a hit.

Wayne Simmonds delivered perhaps the biggest one at the Linc since Brian Dawkins roamed the Eagles' secondary when he plowed Penguins defenseman Brian Dumoulin into the boards with a shoulder to the head. Dumoulin dropped to the ice while a melee escalated around him and the crowd went wild.
