Bergeron got the hat trick with a shot from the slot at 5:36 of the second period to give the Bruins a 6-1 lead. He made it 7-1 with his fourth goal on a one-timer from the slot at 10:45.
"It's just amazing to see [Bergeron] get his shot off from there," Bruins coach Bruce Cassidy said. "If you're at [Warrior Ice Arena, where the Bruins practice] enough, you'll see him working on it every morning skate, getting that quick release. Usually [assistant coach] Jay [Pandolfo] is out there feeding him pucks, or [assistant coach] Joe [Sacco]. And he had four, he may have been able to have six too. He had some really quality looks."
Forward Sebastian Aho, whose 33 points are tied with Teuvo Teravainen for the Hurricanes lead, did not return after sustaining a lower-body injury late in the first period. There was no update on Aho, whose six-game point streak ended.
