Hampus Lindholm made it 3-1 at 7:05 of the second period, scoring from the outside edge of the left circle with a wrist shot that found its way past Ingram’s right shoulder.
Jonathan Aspirot extended the lead to 4-1 at 18:19. Pastrnak skated in on a 2-on-1 rush, toe-dragged Alec Regula, and tried to pass back to Aspirot, who was still able to knock the puck into the open net after it deflected off stick of Darnell Nurse and Ingram's left pad.
Elias Lindholm made it 5-1 at 4:20 of the third period. Alex Steeves passed the puck to Morgan Geekie, who fell to the ice but recovered in time to set up Lindholm for a one-timer that fluttered in off Ingram’s glove.
Roslovic closed the gap to 5-2 at 7:22. He faked a pass to get Swayman off his angle before scoring short side with a wrist shot from the left circle.
“I thought our first period was pretty strong, we just had a couple too many turnovers,” Roslovic said. “We’re a skilled team, we can make plays. You weren’t seeing it tonight, but there’s times to keep it simple, too.”
Pastrnak made it 6-2 at 14:34 with a one-timer from the right circle off a short pass from Minten.
“I was proud of the way we played today and the way we came out,” Bruins coach Marco Sturm said. “I don’t think a lot of people thought we could grab two points here tonight, but we did and in the way we did it, I think that was really good.”
