The Flyers scored five goals in the first period, including three times in a 3:36 span. Weise finished a 2-on-1 rush with Couturier at 4:30, Couturier scored on a rebound of Brandon Manning's shot at 5:49, and Radko Gudas scored on a one-timer from the right point at 8:06.
"We had a great first period," Flyers coach Dave Hakstol said. "We were ready at the start and we got rewarded for it."
Halak replaced Greiss after Gudas' goal but Weal made it 4-0 at 9:19, and Simmonds made it 5-0 with a power-play goal at 15:42. It was Simmonds' 30th goal of the season.
Islanders coach Doug Weight was at a loss for how New York played in the first period.
"It's floating, not engaged with anything," he said. "Just floating through the [defensive] zone, floating through the neutral zone, and then all of a sudden we're like, 'Oh, we're in one here.' I wish I had more to tell you."

The Islanders responded by outshooting the Flyers 22-3 in the second period, but only had Clutterbuck's goal to show for it.
Chimera scored 40 seconds into the third period, and Ladd's shot deflected off Flyers defenseman Ivan Provorov, floated over Mason and rolled off his back to make it 5-3 with 3:58 left.
Filppula's empty-net goal at 18:19 made it 6-3.

"We did good things in the second and third period but the first period wasn't good at all," Islanders defenseman Johnny Boychuk said. "If you can take a positive out of the last two periods, bring it through tomorrow [against the New Jersey Devils] to start the game."
