"We started really well," Barkov said. "We had a lot of shots, a lot of chances to score. That's how we want to play all game. We don't want to take too many penalties."
Continuing to find success with tips and deflections, the Bruins regained their two-goal lead in the third period when Tyler Bertuzzi, who has a point in all four games in the series, re-directed a shot from Brandon Carlo out of the air and through Bobrovsky's five-hole to make it 3-1 at 2:26.
On the power play soon after, the Panthers answered when Sam Bennett fired a rebound past a sprawled-out Ullmark to cut the deficit to 3-2 at 6:11. But less than two minutes later, the Bruins touched the twine again when DeBrusk potted a juicy rebound in the paint to make it 4-2 at 8:05.
With 3:36 remaining in regulation, Taylor Hall scored on a breakaway to make it 5-2.
Shortly after that goal, the bad blood boiled over as chaos erupted around Boston's net with multiple scrums ensuing after Tkachuk was taken down by two Bruins. After getting back to his feet, Tkachuk then got into it with Ullmark, who dropped his gloves and seemed down to dance. Much to the disappoint of fans, the refs squashed the brawl before it could get started.
With 29 seconds left, Hall cashed in on the empty net to lock in the 6-2 final for Boston.
"Just stay out of the box a little more," Panthers defenseman Radko Gudas said. "Play smarter. I thought we were playing pretty hard hockey, so it felt like game could tip both ways. For us, just don't give up. Play as hard as possible and hope for the best."
