Philadelphia was looking for a similar response after a successful road trip and with the chance to move past the Islanders into third place in the Metropolitan Division.
"We weren't at our best on winning battles, going to the dirty areas," Flyers captain Sean Couturier said. "They play a well-structured game, so you've got to give them some credit. I think overall we just need to be better."
The Islanders went ahead 3-0 at 12:50 on DeAngelo's power-play goal. After a Flyers turnover, Duclair led a 3-on-2 rush and dropped the puck to Barzal, who passed across to DeAngelo, who scored on a one-timer from the left face-off circle.
Pageau scored on a one-timer from the slot to make it 4-0 at 13:38 of the third period.
"I thought we were connected," Pageau said. "From the bottom to the top of the lineup, everyone showed up, everyone worked hard. I think we paid a lot of attention to all the little details. We approached the game like it was a playoff game. I thought we played an extremely solid game. Of course, when your goalie gives [up] zero, it helps a lot. He's been amazing for us, and again tonight. But I thought in front of him, a lot of communication on breaking out pucks, a lot of good support, and I thought we played connected in every zone, [defensive] zone, [offensive] zone. They're a good transition team, and then we took that away from them."
