SUNRISE, Fla. -- Two weeks after making his NHL debut, Alan Quine gave the New York Islanders a huge Stanley Cup Playoff victory.
Quine scored a power-play goal at 16:00 of the second overtime, and the Islanders defeated the Florida Panthers 2-1 in Game 5 of the Eastern Conference First Round at BB&T Center on Friday.
"You knew it was going to come down right to the end, and fortunately we got the bounce on the power play from a guy that was in the American Hockey League a month ago," Islanders coach Jack Capuano said.
New York leads the best-of-7 series 3-2. Game 6 will be at Barclays Center on Sunday (7 p.m. ET; NBCSN, CBC, TVA Sports), when the Islanders can win a playoff series for the first time since 1993.

With Panthers forward Derek MacKenzie in the penalty box for slashing, Quine scored on a one-timer from the top of the right circle after taking a feed from defenseman Marek Zidlicky. The puck bounced in off the right post.
"It was opening up for a one-timer, and [Thomas] Hickey made a good play to Zidlicky and he put a nice fake on it and put it right in my wheelhouse and I just ripped it," Quine said. "I put it on net and near the post and saw everyone celebrating a little bit. It was nice for it to go in."
The Islanders won a Game 5 for the first time since 1987, snapping a streak of 11 defeats. The team that wins Game 5 in a series tied 2-2 is 189-52 (78.4 percent), according to Elias Sports Bureau.
The Panthers lost their sixth consecutive overtime playoff game, a streak that includes Game 3 of this series (4-3 on Sunday).
"It's a tough loss," Florida coach Gerard Gallant said. "We played a great game again tonight. The mood is a little bit down, but by the time they get home and they get something to eat, they'll be ready to go back and go to New York and have a great game."

Panthers forward Aleksander Barkov had a penalty shot at 7:19 of the first overtime, but Islanders goalie Thomas Greiss stopped his backhand off a deke. The penalty shot was awarded after it was ruled Islanders defenseman Calvin de Haan closed his hand on the puck in the crease.
It was the third overtime penalty shot in Stanley Cup Playoff history, the first since 1998. All three attempts were unsuccessful. Washington Capitals forward Joe Juneau was stopped by Pittsburgh Penguins goalie Ken Wregget in 1996, and Andy Moog of the Montreal Canadiens stopped Penguins forward Aleksey Morozov in 1998. Panthers forward Jaromir Jagr played in all three games.
The Islanders failed to score on a power play early in the second overtime after Jagr was called for tripping.
"It was a good battle," Panthers defenseman Brian Campbell said. "It's frustrating how it ends, obviously. We had our chances and we're going to continue to have chances. It's just a tough break trying to kill off a couple of penalties in overtime there. Not fun."

Frans Nielsen scored his third goal of the series for the Islanders, and Greiss made 47 saves.
Barkov scored for the Panthers, and Luongo made 40 saves.
Florida trailed 1-0 going into the third period before Barkov tied it at 1:59. He redirected a cross-ice pass from defenseman Alex Petrovic, who scored the go-ahead goal in a 2-1 victory in Game 4. Jagr had the second assist; his streak without a goal in the postseason is 36 games dating to 2012.
The Islanders challenged Barkov's goal for offside, but the play was upheld after review.
Nielsen scored at 13:31 of the first after Panthers goalie Roberto Luongo made a blocker save on his wrist shot. Defenseman Thomas Hickey stopped a clearing attempt by Matheson and shot, but it was blocked in front. The puck came to Nielsen at the side of the net and he put it past Luongo.
Panthers center Vincent Trocheck made his playoff debut. He had been out since March 29 when he injured his foot blocking a shot against the Toronto Maple Leafs. Trocheck began the game at center on the third line between Jiri Hudler and Teddy Purcell before being reunited with Reilly Smith and Jussi Jokinen midway through the second period.
"I thought he was great," Gallant said. "First game back in roughly a month and I thought he competed hard, battled hard and played a real good, solid hockey game. It was great to have him back in our lineup."

Florida center Nick Bjugstad left the game early in the second overtime after his face hit the boards.
"He got some stitches in his head there, I know that," Gallant said. "But besides that, I don't know any more. All I know is he needed stitches and he didn't come back, but I don't think it's that serious. We'll see tomorrow."
The Islanders were without rookie defenseman Ryan Pulock, who will miss the rest of the series with an upper-body injury. He was replaced by Zidlicky.
Quine, 23, made his NHL debut April 9 and played two regular-season games. He had an assist in Game 1.
