"It's pretty special," Pastrnak said. "It's even better with the win. You never know what can happen. I had plenty of games to get there. It's pretty cool, and even better to share with the guys I have here."
Jakub Lauko scored, and Jeremy Swayman made 34 saves for the Bruins (57-11-5), who have won seven in a row. Charlie McAvoy had two assists.
Boston played without forwards Patrice Bergeron and Brad Marchand, and defenseman Hampus Lindholm. Bruins coach Jim Montgomery said the players had nagging injuries.
"With Bergeron and Marchand back home, you could see [Pastrnak's] leadership skills come out," Montgomery said. "I think he put the team on his back and played the right way everywhere."
Montgomery said he does not expect Bergeron, Marchand and Lindholm to miss extended time.
"We didn't have those guys, kind of a no-pressure game really," McAvoy said. "We're not fielding our normal lineup, and to still get a result I thought was great. I thought, really, we were just playing for each other."
Jack Drury, Brady Skjei and Sebastian Aho scored for the Hurricanes (47-16-9), who were coming off a 5-3 win against the Toronto Maple Leafs on Saturday. Frederik Andersen made 35 saves.
Carolina moved three points ahead of the New Jersey Devils, who have played one more game, for first in the Metropolitan Division.
"It wasn't our best game, but I thought in the third period we certainly came on," Hurricanes coach Rod Brind'Amour said. "It's one of those games you probably say it's good to get a point considering how it was looking."
