Mathew Barzal capped a solid all-around effort by the New York Islanders with their season on the line to get a big win.

Barzal scored his second goal of the game on a deflection 1:24 into the second overtime and the Islanders beat the Carolina Hurricanes 3-2 in Game 4 on Saturday to avoid a sweep in their first-round playoff series.

Jean-Gabriel Pageau also scored and Semyon Varlamov stopped 42 shots — including 18 in the overtimes — on his 36th birthday to help the Islanders stave off elimination.

“Our mindset was really good,” Islanders coach Patrick Roy said. “Guys were determined to find a way to fight to win this hockey game. ... It was a team effort. It was about our D played a strong game and we were very good defensively, we were very good offensively.”

Varlamov stopped a shot by Jordan Staal in the opening minute of the second overtime. The Islanders’ Robert Bortuzzo then fired a shot from the point that deflected in off Barzal’s stick for the win.

Bortuzzo said he knew the puck went in when he heard the crowd erupt.

“You didn’t hear anything and then you hear the roar,” he said. “I have not been part of a moment like this. It’s a moment I will remember.”

It was the Islanders’ first overtime goal in the playoffs since Anthony Beauvillier in Game 6 of 2021 Eastern Conference finals against Tampa Bay in the final game at the Nassau Coliseum.
