"[Barzal] moved the puck, got it back, he got open, went to the hard areas, drove the net, and got to the slot," Islanders coach Barry Trotz said. "He didn't try to do it by himself. He trusted his teammates, but he was skating, and he had lots of juice tonight."
Jordan Eberle scored two goals with an assist, and Josh Bailey had a goal and two assists for the Islanders (23-10-4), who defeated the Capitals for the first time in four games this season. Semyon Varlamov made 18 saves.
"When guys are playing to their strengths, that's when the line (Barzal, Eberle, Leo Komarov) goes," Barzal said. "Leo is doing his thing in the corner, getting us the puck. 'Ebs' was making his little plays, getting open, and I was skating. When we're doing those things, it can be a good line."
John Carlson scored two goals, and Daniel Sprong had a goal and an assist for the Capitals (23-9-4).
"I do think we did things that shot ourselves in the foot with regard to puck movement and coverage," Washington coach Peter Laviolette said. "We just lost a game; we gave up eight goals. You look to fix that and be better the next night."
