NEW YORK -- The Boston Bruins extended their season-long point streak to nine games by defeating the New York Islanders 5-1 at Barclays Center on Tuesday.
The Bruins (22-10-4) have won back-to-back games and are 7-0-2 since Dec. 16. It's their first streak of at least nine games with a point since the 2014-15 season, when they were 6-0-3 from Dec. 29-Jan. 15.
Boston got goals from three lines, including from first-liners Patrice Bergeron and Brad Marchand and from fourth-liners Tim Schaller and Noel Acciari. Third-line left wing Danton Heinen also scored.

Tuukka Rask, who was named the NHL's First Star of the Month for December on Tuesday, made 25 saves. Rask is 10-0-1 since Nov. 29 and hasn't allowed more than one goal in any of his past five starts.
"We're confident right now," Marchand said. "We're confident in our ability. We knew it was coming this year. We had a lot of injuries [early in the season]. We knew we just needed some time to come together a bit. You see the way some young guys are stepping up, it just seems like everyone is connecting. Everyone has that chemistry."

Jaroslav Halak made 33 saves and Jordan Eberle scored an unassisted goal for the Islanders (20-16-4), who have been outscored 15-4 in three straight regulation losses. It's the first time this season the Islanders have gone three straight games without a point.
Islanders coach Doug Weight said he is especially unhappy with the lack of passion being displayed by his team, which has fallen out of a Stanley Cup Playoff position.
"Adversity is hitting us between the eyes," Weight said. "We've got to find a way. If you're going to use words like flat or a little sluggish at times, getting overpowered, it's concerning, but it's not going away. We've got to figure it out. We've got to go to work [Wednesday] and get back our mojo, our fierceness we seem to have let drift."
Bergeron gave the Bruins a 2-1 lead at 8:28 of the second period. It wound up as the game-winning goal.
He went behind the net after delivering a pass to Marchand in the slot. Marchand's shot ricocheted up and over the net. Bergeron knocked it down with his left hand and from the goal line banked the puck off Halak's right skate and into the net for his 12th of the season.
"It was a very high IQ play there," Bruins coach Bruce Cassidy said.
Bergeron said he curled behind the net because he saw the puck pop in the air.

"As soon as it was in the air, I saw that the goalie wasn't necessarily in position and ready for it," Bergeron said. "I was trying to put the puck down on the ice as quickly as possible, get it on net and hope for the best. It worked out."
The Bruins outshot the Islanders 17-8 in the second period largely by controlling the puck in the offensive zone with a strong cycle game and an aggressive forecheck. Cassidy said the fourth line of Schaller, Acciari and Sean Kuraly set the tone.
"When we get buzzing we're a decent forechecking team," Cassidy said. "We've got some heavy lines and our skill lines are good at handling the puck. I think our guys have bought into it, understand that we can be real effective that way, that we're hard to get it from. Some of our defense tonight came from just good puck possession in the offensive zone."
The work of wearing down the Islanders paid off in the third, when Boston scored three goals.

Marchand extended the lead to 3-1 by converting off a 2-on-1 rush with David Pastrnak at 9:04. Schaller scored his fifth of the season at 15:02 and Acciari scored an empty-net goal at 17:47.
"It takes a toll on a team after a while," Cassidy said.
Boston gained a 1-0 lead on Heinen's 10th at 8:17 of the first period. Eberle scored 1:13 later.
