"We wanted to play a certain way," Islanders coach Barry Trotz said. "We talked about culture and identity. We tried to create that with what we felt we had. We didn't know a lot about our goaltending. We didn't know a lot about our defense. ... Getting everybody to play for each other is a hard thing. Understanding that you just do your job, do it well, do it for the guy next to you."
Jordan Eberle scored for the fourth straight game, Brock Nelson scored his third goal of the playoffs and Robin Lehner made 32 saves for New York.

Jake Guentzel scored for Pittsburgh, which was swept for the first time since the 2013 Eastern Conference Final against the Boston Bruins. Matt Murray made 23 saves.
"We knew the type of game [the Islanders] were going to play and what we were up against," Penguins coach Mike Sullivan said. "You can use any vocabulary you want to describe it. We talked about having patience with our game and taking what the game gives us and making better decisions with the puck so we don't put ourselves in some difficult circumstances. Unfortunately, we put ourselves in some difficult circumstances."
Guentzel gave the Penguins a 1-0 lead 35 seconds into the first period Guentzel took a pass from Sidney Crosby and scored on a wrist shot from the left face-off circle for his only playoff point after scoring 40 goals in the regular season.

The assist was Crosby's one point of the playoffs after having 100 points (35 goals, 65 assists) in the regular season. His previous playoff low was four points (two goals, two assists) in five games against the New York Rangers in 2015.
"It's obviously frustrating," Crosby said. "I haven't had a lot of time to digest it. Just disappointing. I think we felt good about our game coming into the playoffs and were playing some good hockey. And then got off to a rough start, but still felt like we had a chance here coming home."

Eberle tied it 1:34 later. Mathew Barzal carried the puck on a 2-on-1 before passing to Eberle, who scored at 2:09.
"[The series] was definitely closer than it looked," Eberle said. "We had to really work to try to get above them, try to frustrate them and try to limit their chances. Obviously, [Lehner] was huge back there. ... Anytime they had a chance, he was there to stop them."
The Penguins had a 1-0 lead in each of the final three games. Those leads lasted a combined 4:51.
Nelson put the Islanders ahead 2-1 with 1:54 remaining in the first. Tom Kuhnhackl tipped the puck away from Penguins defenseman Marcus Pettersson behind the net, allowing Josh Bailey to take it and pass to Nelson in front for a wrist shot.
Bailey scored an empty-net goal, making it 3-1 with 38 seconds remaining in the third period.

They said it

"It was four really tight games. Even if we won four, they were down to the wire, every single one of them. You get that sense of relief a little bit because they're a [heck] of a hockey team. ... You don't want to give them life. So there were some nerves there in the end, but we stuck together." -- Islanders goalie Robin Lehner
"They played well and they played hard. They defend hard. So maybe sometimes, with the puck, we were careless. But I thought we played well the last couple games. It just didn't go our way." -- Penguins forward Jake Guentzel
