Derek Stepan and Seth Jarvis scored, and Pyotr Kochetkov made seven saves in relief of Antti Raanta to give the Hurricanes their fourth consecutive victory. They tied a Carolina/Hartford Whalers record for wins and points (112) in a season, set by the 2005-06 Stanley Cup champions.
Raanta made 17 saves before leaving with a lower-body injury at 12:57 of the second. Frederik Andersen has missed four games with a lower-body injury and will be reevaluated in the next few days.
"I thought 'Raants' was really good for us and when (Kochetkov) came in, I think everyone kind of tightened up to help out a teammate," Stepan said. "It just sharpened us a little bit. That's all it takes nowadays in this game, is a little bit of elevation, and it can be the difference in a lot. The little sharpening was huge for us."
Ross Johnston and Ryan Pulock scored, and Semyon Varlamov made 29 saves for the Islanders (35-34-10), who have lost five in a row (0-4-1).
"[The Hurricanes] want to finish first, and I thought we played them straight up," New York coach Barry Trotz said. "For two periods, I thought we were really quite good. We battled back and got ourselves to a 2-2 game."
