Brock Nelson scored the Islanders' first goal in three games when he knocked a puck out of the air past Hart to make it 1-1 at 14:27 of the first. It ended New York's goal drought at 134:27, dating to Nelson's goal in overtime against the Minnesota Wild in a 3-2 win on Sunday.
"Obviously tough bounce (on Hagg's goal), one we'd like to have back," Nelson said. "When things aren't going your way, you can sit back and think, 'Here we go again.' I think everyone did a good job getting back skating, keeping it simple. We had some good [offensive] zone time, had some good looks, were able to get that one and I think that was a big one for us."
Nick Leddy put the Islanders ahead 2-1 at 10:58 of the second period when he one-timed a pass from Mathew Barzal past Hart.
