Dvorak cut it to 2-1 at 10:29. He left the puck for Matvei Michkov at New York’s blue line, skated to the net and was open to score off a pass from Zegras.
Roy felt Dvorak’s goal was a turning point.
"I thought that we were playing really well, even if they had a little more shots than us," he said. "It was 2-0 us, and it's too bad that we lost our coverage on that goal and gave them a bit of life."
Zegras’ first goal with the Flyers tied it 2-2 at 1:54 of the third period. Dvorak was able to control a bouncing puck and passed back to Zegras, who scored from the bottom of the right face-off circle.
"I saw him when I got the puck, saw him out of the corner of my eye," Dvorak said. "He called for it too. Good communication. He was in a good spot and put it in."
Maxim Tsyplakov put the Islanders back in front 3-2 at 4:21, redirecting Warren's point shot.
But Zegras tied it 3-3 at 7:32, knocking a loose puck in the crease under Sorokin after Islanders defenseman Scott Mayfield was penalized for high-sticking.
"That's a big goal, Trevor digging in the crease and getting that goal," Philadelphia coach Rick Tocchet said. "It's hard. You're blocking out the noise and it's hard to do, but he stuck with it. That's what's got to happen."
Zegras scored low blocker on Sorokin in the second round of the shootout, and Michkov scored in the third round. Holmstrom scored in the second round for New York.
