PHILADELPHIA -- The New York Islanders rallied from three goals down in the third period and extended their point streak to 14 games with a 4-3 shootout win against the Philadelphia Flyers at Wells Fargo Center on Saturday.
Anthony Beauvillier had two goals, and Mathew Barzal also scored for New York (14-3-1), which trailed 3-0 after the second period. Thomas Greiss made 28 saves.
The Islanders are 13-0-1 in their past 14 games, their longest streak since winning 15 in a row from Jan. 21-Feb. 20, 1982.
"We were definitely in a hole there going into the third," Barzal said. "At that point, you just want to go out and get one and go from there. ... I don't know what it is with this group. We knew we'd be in the fight right to the end, and that's what we did tonight."

Sean Couturier, Ivan Provorov and Oskar Lindblom each had a goal and an assist for Philadelphia (10-6-4). Brian Elliott made 33 saves.
"We did not play the way we need to play [in the third period]," Provorov said. "We sat back and started making mistakes, turning the puck over in the neutral zone and not getting the puck out of our zone when we needed to."
New York tied the game with 2:04 left when Beauvillier's second goal of the game bounced past Elliott.
"Just trying to get it on net," Beauvillier said. "Good bounce. One of those bounces you're happy to have them when they come."
He scored the Islanders' first goal when a bad Flyers line change allowed him to break in on Elliott and slide a puck along the ice between his pads at 7:46 of the third.

Beauvillier has four goals in two games after going 14 games without one.
"I think he's just using his assets," Islanders coach Barry Trotz said. "He's a great skater, he's got confidence with the puck, he's got nice hands, he can score. And he's going to the hard areas. And because he's going to the hard areas, he's getting rewarded."
Barzal made it 3-2 with 6:26 remaining with a power-play goal that extended his point streak to four games (three goals, three assists).
Jordan Eberle and Barzal scored in the shootout for New York. Greiss made saves against Couturier and Claude Giroux.

Couturier gave the Flyers a 1-0 lead with a shot from between the top of the circles at 1:38 of the first period.
Provorov made it 2-0 when he one-timed a pass from Couturier past Greiss for a power-play goal at 19:35 of the first.
Lindblom scored when Provorov stepped up in the neutral zone to force a turnover. Joel Farabee pushed the puck ahead to Lindblom, and his shot beat Greiss past his glove at 12:20 of the second period to make it 3-0.
It's the fourth time in six games the Flyers have held a multigoal lead but ended up playing past regulation.
"You've just got to close out games," Elliott said. "There's little plays like getting the puck out when you have a chance, allowing guys to change, just keeping fresh bodies on the ice and not getting stuck out there."
They said it
"The way we played in the second, there was definitely belief and hope because we had some momentum. It wasn't like we were getting outplayed the whole time. ... We had chances and looks and just didn't capitalize." -- Islanders center Brock Nelson
"You have to be able to come out with a win. Three goals in the third period is a big thing to give up. I think we have to dial in a little bit more and play a better third." -- Flyers forward Joel Farabee
