Gordon said killing the four straight minutes, which carried into the opening 45 seconds of the third period, gave the Flyers a lift.
"To leave the ice (after the second period) and have the fans cheering, and when it was finished start of the third period, same thing," he said. "You can feel the emotion from the crowd, and that carries to the bench. Guys watching players sacrifice themselves to block the shots, it's a tremendous effort."
Voracek scored at 5:10 of the first period to give Philadelphia a 1-0 lead.

"I think we're putting a lot more pressure than we did 10 games ago and don't let them set up," Hagg said. "Because they're skilled guys out there, every team in the League. So take away time and space for them and don't let them set up. That's the biggest thing."
