Mathew Barzal scored once in a three-point game and John Tavares netted the overtime winner in a two-goal outing as the New York Islanders claimed a 5-4 win over the Montreal Canadiens Monday night in Montreal.
Islanders backup goalie Thomas Greiss stopped 52 shots for his first victory in nearly a month as the Islanders claimed a third straight win.
The Islanders twice blew two-goal leads at the Bell Centre. Anthony Beauvillier, on his team’s first shot, and Barzal tallied early first-period goals to spot the Islanders a 2-0 lead, but Nicolas Deslauriers and Paul Byron both scored to draw the Habs even before the first intermission.
The Islanders again figured they were off and running to victory when Adam Pelech and Tavares each lit the lamp to give the visitors a 4-2 lead. However, Jonathan Drouin broke a 12-game goal slump in the final minute of the second period and Max Pacioretty added a power-play goal with seven minutes remaining in regulation to force overtime. Pacioretty has scored in four consecutive games.
Barzal, who had a five-point outing in a 7-2 shellacking of the New York Rangers on Saturday, leads all rookie NHLers with 47 points in 45 games. Jordan Eberle collected a pair of assists.
Defenseman Jakub Jerabek collected his first NHL point in a two-assist game for the Canadiens, who have just two wins in their last nine games. Carey Price was victimized four times on the first 10 shots and made 19 saves for Montreal.
Montreal forward Phillip Danault, who was sent to the hospital after being hit in the head by a puck shot by Boston’s Zdeno Chara on Saturday, didn’t play and is sidelined with a concussion.
The Canadiens also were without forward Andrew Shaw, who has been sidelined with a lower-body injury. They acquired forward Logan Shaw off waivers from the Anaheim Ducks, but he didn’t play. New York defenseman Scott Mayfield left the game late in the second period after he attempted to block a shot with his stick only to have the puck deflect into his mouth.
Tyler Seguin beat his old team Monday with a wrister at 2:59 into overtime, giving the Dallas Stars a 3-2 win over the Boston Bruins at TD Garden.
Seguin’s 22nd goal of the season was set up by John Klingberg and Jamie Benn. For Klingberg, it was his 35th assist, tops among all defenseman. It was Benn’s second helper of the game.
With the win, the Stars begin a four-game road trip through the Eastern Conference with a two-point day. 
The Bruins forced overtime with Ryan Spooner’s fifth goal off a point blast at 11:21 of the third period. Kari Lehtonen made the initial save on Spooner’s shot, but the puck appeared to bounce off a Stars defender and trickled just past the goal line.
Lehtonen was solid most of the game, though, coming up with 30 saves to earn the win. Anton Khudobin was saddled with the defeat for Boston after stopping 29 of 32 shots.
Nathan MacKinnon continues to score and Colorado is now riding a seven-game winning streak thanks to a 3-1 victory over Anaheim in Denver.
MacKinnon’s tally midway through the second period served as the winner and capped a wild stretch at the Pepsi Center. Avalanche goalie Jonathan Bernier was under siege but made a series of stops - including a fantastic desperation diving save on Ryan Kesler - seconds before MacKinnon used a defender as a screen as he whipped home a shot from the slot for his 20th goal of the season.
