BUFFALO -- The Buffalo Sabres scored five goals in the first period and extended their point streak to four games in a 7-1 win against the New Jersey Devils at KeyBank Center on Monday.
Linus Ullmark made 44 saves, Jack Eichel had a goal and two assists and Conor Sheary scored twice for Buffalo (13-10-5), which is 2-0-2 in its past four games. Johan Larsson had three assists.
"The last couple of weeks, we think we've been playing pretty good hockey," said Sheary, who ended a 19-game goal drought. "We haven't gotten a lot of results, and part of that is because of secondary scoring. The other part is special teams, and both of those were good tonight. Hopefully that will give us confidence moving forward."

Louis Domingue allowed five goals on 15 shots and was pulled after the first period for New Jersey (9-13-4), which has lost five of its past seven games and was without Jack Hughes for a second straight because of a lower-body injury. Mackenzie Blackwood made 15 saves in relief.
"I'm running out of things to say as to why we're playing like that," Devils forward Taylor Hall said. "It's hard. It's a tough pill to swallow, and it's everyone in here. It's too bad. We have the players in here to play a lot better than that. We've got to step it up."
Eichel opened the scoring when his shot trickled between Domingue's pads to give Buffalo a 1-0 lead at 2:46 of the first period.
Jeff Skinner made it 2-0 when he capitalized on a turnover at 4:59.
Sheary scored on a rebound of Skinner's shot to give the Sabres a 3-0 lead at 6:57, then made it 4-0 at 16:41 when his shot from the left circle popped up and hit Domingue's blocker before falling into the net.
Rasmus Asplund's first NHL goal gave Buffalo a 5-0 lead at 19:02.

New Jersey allowed five goals in the first period for the first time since Feb. 9, 1993 (8-5 loss to the Detroit Red Wings).
"The first period was not close to being good enough in any area, and obviously the scoreboard said it and it's unacceptable," Devils coach John Hynes said.
Victor Olofsson finished a give-and-go with Brandon Montour with a one-timer from the right circle to make it 6-0 at 4:40 of the second period.
Nico Hischier got the Devils on the board at 8:10 of the second period on a rebound for a power-play goal to make it 6-1.

Henri Jokiharju scored with a slap shot from inside the blue line on the power play at 12:08 of the second for the 7-1 final.
New Jersey outshot Buffalo 21-8 in the second period, and Ullmark made 18 saves in the third.
"I thought they did a good job of managing it with 5-0," Buffalo coach Ralph Krueger said. "We haven't been in that position before, and Linus did a good job too. It was nice to see the guys explode. [It was] nice to see Asplund get his first goal, good to see Sheary get a couple, [Jokiharju] on the power play. Just a lot of things happening today that we can build on."
They said it
"Mistakes, miscues. That's really what it comes down to. I don't know if we're trying too hard or if we're not competing hard enough. It's hard to say. But right now we've got to find some kind of edge, and right now we don't have it." -- Devils forward Taylor Hall
"I think the coaches, they're able to give us confidence throughout the lineup. Game in, game out, they have the same message no matter what happened the game before. We're never looking too far ahead, we're staying in the moment and I think that could be helpful for me." -- Sabres forward Conor Sheary
