UNIONDALE, N.Y. — After two tough losses, the New York Islanders turned back to Ilya Sorokin in a game they needed to win, and the rookie goalie came through.

Sorokin stopped 29 shots, Oliver Wahlstrom and Ryan Pulock each had a goal and an assist and the Islanders beat the Pittsburgh Penguins 4-1 in Game 4 on Saturday to even the first-round series.

Sorokin, who had 39 saves in the Islanders’ 4-3 win in Game 1, was back in goal after Semyon Varlamov started Games 2 and 3 — both losses.

“Ilya’s been through a lot of stuff, everything from league championships in a very good league in the KHL,” New York coach Barry Trotz said. “He’s won it, he’s been MVP. He’s been under the spotlight a lot and been in those big moments. ... He’s not a guy that’s a pure rookie coming in the NHL or a lot of these high-pressure situations. He’s had a lot of them, just in different leagues.”

Josh Bailey and Jordan Eberle also scored and Mathew Barzal had two assists for New York.

Tristan Jarry had 23 saves for Pittsburgh, and drew mocking chants of “Jar-ry! Jar-ry!” from Islanders fans.

“We just got to stay with it,” Penguins coach Mike Sullivan said. “I don’t think we were quite as sharp tonight. We didn’t have as many looks tonight as we had in the first few games. We’re going to have to work for those moving forward.”

Game 5 is Monday night in Pittsburgh, and Game 6 back at Nassau Coliseum on Wednesday.

With the teams skating 4 on 4 in the third period, Pittsburgh’s Kris Letang was whistled for interference to put the Islanders on their third power play. Just as a penalty on Scott Mayfield was expiring, Wahlstrom fired a one-timer that was stopped by Jarry, However, Pittsburgh’s Teddy Blueger knocked the puck in while trying to clear the rebound, putting New York up 3-0 at 6:04.

With the Islanders still on a power play, Eberle made it 4-0 just 24 seconds later as he beat Jarry high on the glove side from the inside edge of the right circle.

“It’s a critical moment in the game,” Barzal said. “(If) they kill that off they got a lot of life. Just two huge goals to put the game away. That’s a crucial moment, big by our power play.”

Zach Aston-Reese spoiled Sorokin’s shutout bid with a short-handed goal with 2:35 to go. It was his first career playoff goal.

The Islanders expect the Penguins to come out refocused back on their home ice Monday night.

“It’s a pretty veteran group over on the other side,” Barzal said. “I think whatever we did tonight, they’ve probably already forgotten about it. They’re going to be fresh for Game 5. “
