NEW YORK -- Anthony Beauvillier scored his second goal of the game with 2:08 remaining in overtime, and the New York Islanders rallied for a 4-3 win against the Dallas Stars at Barclays Center on Tuesday.
Mathew Barzal tied the game with 3:59 remaining in the third period for New York (30-15-6), which extended its point streak to four games (2-0-2). Semyon Varlamov made 28 saves.
"We have a lot of character in this room," said Beauvillier, who has 15 goals this season. "It showed tonight again. [Barzal] came up big for us. A huge two points for us tonight."

Beauvillier won it with a breakaway after Barzal tied it on the power play when he shot the puck between his legs near the left post make it 3-3.
The goal came after Brock Nelson had a goal taken away with 5:27 left when the Stars won a coach's challenge for goalie interference by Islanders forward Anders Lee.
"We were pretty calm," Barzal said. "At that point you can't really do anything; it was just an unfortunate bounce. I haven't seen the replay, but I'm sure they got [the call] right, but a big bounce-back by our power play."

Ben Bishop made 37 saves for Dallas (30-18-5), which finished 2-0-1 on its three-game road trip. The Stars were playing their second game in as many nights following a 5-3 win at the New York Rangers on Monday.
"You're going to sit here and say five [points] out of six is great, but you just don't like giving up that last point, I'll tell you that," Stars coach Rick Bowness said. … "You can't beat yourself in that third game. We had the chance to take the six [points] out of six, and it's disappointing we didn't."
John Klingberg gave the Stars a 3-2 lead at 6:56 of the third with a shot from the right point that found its way through traffic.
Beauvillier gave the Islanders a 1-0 lead at 1:30 of the first period when he took a saucer pass from Jordan Eberle and scored on a backhand for his second goal in three games.

Denis Gurianov tied it 1-1 on the power play when he one-timed a no-look backhand pass from Corey Perry at 14:08.
The Islanders outshot the Stars 18-8 in the first period.
"We expected to have a slow start," Bowness said. "It's our third game in four nights, they're sitting here rested and waiting for us. We played ourselves through that. We were fine after that."
Jason Dickinson gave Dallas a 2-1 lead with a wrist shot from the slot after a pass from Andrew Cogliano at 12:12 of the second.
Derick Brassard quickly tied it 2-2 when his shot from beyond the goal line squeaked past Bishop at 13:38. It was his first goal since Dec. 17 (19 games).
"It's just one of those things that finds a little hole there," Bishop said. "I wouldn't really do much different. Sometimes they just go in, unfortunately. You'd like to make that save. … I'm not too happy with the bounces tonight, but all in all, we'll take the point."

Islanders forward Kieffer Bellows made his NHL debut and had an assist on Brassard's goal for his first point. He is the son of Brian Bellows, who played 17 seasons in the NHL.
"I thought just even getting that first shift out of the way, getting a nice hit in and a shot, that really just brings a comfort factor," Bellows said. "Playing with [Brassard] and [Michael Dal Colle], those guys are two really great guys and two great linemates that just stay positive the whole time. It's a lot of fun playing with them."
