The win snapped a four-game losing streak and ended a streak where the Islanders failed to tally more than one goal in each of their previous four games.
"It's a good win. It's good for the guys," Jack Capuano said. "It's another game. It's good to get rewarded. I thought we've played extremely well. We've actually dominated some of the games that we lost and we have a tough stretch coming up with Minnesota... I'm glad we came in here, we were structured and I thought they executed the game plan with what needed to be done against a structured Devils team."
The Islanders jumped on the board nearly eight minutes into the game. Nikolay Kulemin forced a turnover and fed the puck to Ryan Strome. The Isles' forward snapped the puck past Corey Schneider to give the visitors a 1-0 advantage.
It was the first time the Islanders had a first period lead since March 10 against the New York Rangers.
"It was a good play by [Kulemin]," said Strome, who finished the game with two points (one goal, one assist). "I was calling for it and that's his bread and butter that forecheck. He kind of gets pucks back and great play by him."
The Islanders maintained the lead for the rest of the first period and the entirety of the second. The Devils generated some chances in the game's second frame and came within inches of of tying the contest. A shot from Travis Zajac beat Jaroslav Halak, but the puck hit the iron and stayed out of the net.
Halak faced a few more Devil shots, but ultimately kept them out and finished with 26 saves.
The visitors from Long Island got some insurance midway through the third period. Seconds after an Islander power-play ended, Travis Hamonic fired the puck into the Devils net and give the Islanders a 2-0 lead and sending Isles fans at The Rock into a frenzy of "YES!" chants.
Kyle Okposo scored on an empty in the final minute.
Saturday was night of things going right for the Isles. Halak played a strong game between the pipes to record a shutout, the Islanders were able to score multiple goals and Strome performed well. Stromes two-point night was his first since February 16 against the New York Rangers and his goal was his first since February 27 against Calgary.
"It feels good," Strome said about getting back on the score sheet. "That confidence last couple of games has been up and down, so kind of good to get one. To bang one in feels really good, that's for sure."
