Nico Hischier scored, and Mackenzie Blackwood made 32 saves for the Devils (4-5-4), who are 2-0-2 in their past four games and have begun a five-game road trip with their first two road wins of the season (2-3-0). They defeated the Carolina Hurricanes 5-3 on Saturday.
"I think we knew in the locker room if we keep playing the way we can play we'll get those wins, and now they're coming," Hischier said. "It's a big one on the road for us, but we've got a couple more road games ahead, so we've got to come out the same way like we did in the first period today."

Andrew Copp scored, and Connor Hellebuyck made 31 saves for the Jets (8-7-1).
"I feel we hold ourselves to a pretty high standard and didn't play all the way up to that," Copp said. "It's not like we were off by a lot. We did some good things. Obviously played pretty well defensively. [Hellebuyck] was great again. Some good things, but we've got to keep building."
Hischier made it 1-0 on a backhand at 4:44 of the first period, sliding a loose puck past Hellebuyck.
"We know it's not always going to be easy," Hischier said. "[There's] nice goals. Sometimes you get those dirty goals, too, and they feel even better."
Copp tied it 1-1 at 8:38 of the second period, deflecting Josh Morrissey's shot from the left point.
"I thought we got better as the game went on," Jets coach Paul Maurice said of Winnipeg, which outshot New Jersey 25-20 after the first period. "I liked our third better than our second better than our first, so I thought we had a bit of a push there and had some chances."
