UNIONDALE, N.Y. — Josh Bailey scored on a rebound at 4:39 of overtime and the New York Islanders beat the Pittsburgh Penguins 4-3 on Wednesday night in the opener of their Eastern Conference first-round playoff series.

Jordan Eberle had a goal and an assist, and Brock Nelson and Nick Leddy also scored for New York, which was opening a postseason series at home for the first time in 31 years. Robin Lehner stopped 41 shots.

Phil Kessel and Evgeni Malkin each had a goal and an assist, and Justin Schultz also scored for the Penguins. Matt Murray finished with 29 saves.

On the winning goal, Barzal brought the puck into the offensive zone on a 2-on-1 break, faked in front to draw Murray out and sent a backhand shot that bounced off the left post, but Bailey was there to knock it in.

Game 2 is Friday night back at the Nassau Coliseum.

Tom Kuhnhackl, who had a goal in the opening minute of the game waved off for offside, nearly won it for the Islanders 1:12 into the extra period as he crashed into Murray and the puck crossed the goal line but not before the net came loose. The no-goal was confirmed after a review.

The Islanders led three times in regulation with the Penguins managing to tie it each time.

Leddy gave the Islanders a 3-2 lead with 7:25 left in the third as he sent a long shot from left point at the blue line that knuckled past Murray.

With Murray pulled for an extra skater, Schultz fired a one-timer from the left circle past Lehner inside the left post with 1:29 left as the Penguins tied the score for the third time.

Bailey had a chance at the winner for the Islanders in the closing seconds of the third, but his shot hit the right post. It was the second time in the period a New York player hit a goal post as Matt Martin did it in the opening minute.

Malkin tied it 2-2 on a power play with 6:19 left in the middle period as his shot from the inside edge of the right circle deflected off Islander defenseman Adam Pelech’s stick and up past Lehner.

Pittsburgh outshot New York 17-12 in the first period, but the Islanders led 2-1 after 20 minutes.

Just more than a minute after Kuhnhackl’s opening-minute goal was overturned, Eberle did give the Islanders the lead as he beat Murray at 1:40.
