The Islanders had played a lot of catchup against the Flyers in their three previous meetings, falling behind by at least two goals in each contest. That was not the case on Saturday, as the Islanders stormed out of the gates to go up 3-0 by the 10:03 mark.
Pageau started the goal parade, tucking in an Oliver Wahlstrom rebound for a power-play goal at 6:11. The goal was Pageau's 10th of the season and snapped a nine-game goal drought.
The Islanders made it 2-0 less than two minutes later, as Eberle also netted his 10th goal of the campaign. Thomas Hickey, playing his first game in nearly two years, circled the net and throw the puck into traffic and after Mat Barzal was denied, Eberle corralled and deposited the loose puck.
Cizikas put an exclamation point on the first half of the first period, stealing the puck of Nate Prosser at the Flyers blue line, skating in and snapping a low shot far side on Carter Hart.
"It speaks to the group of guys that we have," Cizikas said of the bounce-back effort. "The way that we came out here tonight and battled for each other was the biggest key. We went out there and we established what we wanted to right off the hop and we continued that for 60 minutes."
Alain Vigneault called a timeout after Cizikas' first goal, but it was the Islanders who scored next, as Cizikas deposited his second of the period off a Hickey rebound.
With the Flyers' 9-0 loss to the Rangers on Wednesday still fresh, Joel Farabee ensured the Flyers would not be shut out again, beating Ilya Sorokin with a wrister on a two-on-one at 17:52.
Playing with the lead for the first time against the Flyers this season, the Islanders put the game into cruise control. They held the Flyers at bay in a scoreless second period - that saw Philly outshoot them 11-7 - and then locked it down in the third, holding the Flyers to three shots in the final frame.
Beauvillier effectively iced the game at 9:45 of the third, intercepting Prosser's clearing attempt before potting his first goal in 10 games. Bailey got one for good measure on a similar play, intercepting Hart's clearing attempt before sliding a puck into the yawning cage.
