"I thought both teams dealt with the same opportunities for distractions with guys being taken out of the lineup, and I thought that our group was mentally ready to play," New Jersey coach John Hynes said. "I thought we had a real strong care factor going into the game and that allowed us to get off to a good start."
Zajac scored on a tip-in from the slot at 11:45 of the first period to give New Jersey a 1-0 lead.
Santini scored his first goal since Dec. 15, 2017, on a slap shot from the point to make it 2-0 at 14:34.
"It's a pretty emotional day because you come to the rink and you don't know if you're playing and then you find out you're playing," Santini said. "To get a goal like that and help us get off to a good start felt really good."
Gabriel made it 3-0 when he scored his first NHL goal on a wrist shot from the left face-off circle at 3:40 of the second period.
"Everyone knows my job isn't scoring goals but of course if I can chip in, I will," Gabriel said. "I work on my shot all the time and they're always encouraging me to shoot every time in practice, letting me know when I make nice plays. They're trusting me and that builds my confidence."
Wood scored on a redirection from the slot to make it 4-0 at 14:52.
