The Islanders (26-34-9) earned their 10th home win (10-17-8), and did it in a rare matchup against an opponent they are ahead of in the standings.
Backup goalie Anders Nilsson (3-4-2) earned the win in his 15th NHL game. He lost his shutout bid 56 seconds into the third when Tyler Ennis scored a power-play goal.
But the Islanders' two-goal lead was restored 39 seconds later when Ryan Strome scored his fourth goal. Cal Clutterbuck added an empty-netter with 2:13 remaining.
Nilsson made 33 saves while subbing for No. 1 netminder Evgeni Nabokov, who lost 4-3 to San Jose on Friday.
