The Devils were 3-for-3 on the power play and 4-for-4 on the penalty kill.
“They gained a ton of momentum on their penalty kill and their power play," said New York coach Mike Sullivan, who also was the Team USA coach. "A big part of this game is momentum, and we didn’t get any juice from our special teams today.”
Will Borgen, Vladislav Gavrikov and Will Cuylle scored for New York (24-30-8), which was 2-0-2 in its previous four games. Jonathan Quick made 29 saves.
“I think the world of Jack," Sullivan said. "He’s a really good player, he’s a great person. But when we play him, we want to beat him. He’s a dangerous guy in particular on power plays, and we just gave him too many looks."
Nico Hischier scored a power-play goal on a rebound in the slot to give the Devils a 4-3 lead at 8:05 of the third period.
"Sometimes they go in, sometimes they don't, but I think what the difference on the power play is we're making more right decisions," said Hischier, the New Jersey captain. "Obviously when you make more right decisions on the power play, you give yourself more chances to score goals and that's the biggest difference."
Hughes took a lead pass from Brown and scored on a breakaway for a 5-3 lead at 16:56 before scoring an empty-net goal at 19:28 for the 6-3 final.
"[The reason for our success of late is] we're healthy," Hughes said. "We haven't been healthy since November, so we're finally healthy. I think guys are confident and when the group starts to roll, everyone's feeling good about their game, the group's feeling better about themselves. I think we're in a good groove right now but it's all about just being present, staying in the moment and keeping at it."
Bratt gave the Devils a 1-0 lead at 1:06 of the first period, scoring on a one-timer from the low in the right face-off circle off a cross-ice pass by Cody Glass.
