Prince scored at 3:15 of the third period to give the Islanders a 1-0 lead. His fourth goal of the season came off a pass from Casey Cizikas, who picked off Capitals defenseman Dmitry Orlov at center ice to start the play.
"We all knew going into the third period it was going to be a tight game," Halak said. "We just said in the locker room, 'Let's just get this one, let's just get the two points.' I think we did a great job coming out in the third period scoring a couple quick goals, and it always puts the other team on their heels. From that moment, I think we controlled the game."

Nelson scored at 6:43 for a 2-0 lead. He capitalized on an Orlov turnover to score his sixth goal of the season. Chimera scored at 7:43 to make it 3-0, his third goal of the season.
Washington was 0-for-6 on the power play.
"Give credit to the Islanders," Capitals coach Barry Trotz said. "They do a good job getting in the lanes, there's a big commitment to do that. If the lane opens up, once it's in your hands, you've got to deliver it."

They said it
"We were attacking. It's just the way we've played in the past. We played to our identity. I thought we managed the puck much better. They still had a few chances. The goalie made some saves, but, again, it's just the way we're used to playing and trying to find our way here with that process, our foundation that we need to play with. It was just a great effort back-to-back nights against two really good hockey teams." -- Islanders coach Jack Capuano on the third period

"If your power play's clicking, it can be a real intimidating thing, and our power play has been intimidating in the past few years. This year the numbers aren't illustrating that it's intimidating right now, but chances, entries … I keep telling everybody that the numbers are the same, if not better, but we're not taking those opportunities and putting them through the back of the net." -- Capitals coach Barry Trotz
"It's never easy to score goals, for sure, especially on a Vezina Trophy winner. You've got to make perfect shots. Hats off to Braden. He's one of my good friends, and he's tough to beat. You've got to make a perfect play to beat him." -- Islanders forward Jason Chimera on scoring on former teammate Braden Holtby
