Bruins forward David Pastrnak did not make a substitution during the third period, but remained on the bench in what Montgomery called a “coach’s decision” before declining to comment further.

Joey Daccord made 31 saves for Seattle (5-7-1), which has lost three straight and six of its last seven (1-5-1), including a 3-0 loss to the Ottawa Senators on Saturday.

“(The Bruins) are always a fast-starting team at home, and yes, they took advantage of their opportunities early in the game,” said Daccord, a Boston native. “We just have to stay positive. It’s early in the year. Before you know it, we’ll find our game here.”

Brazeau gave the Bruins a 1-0 lead at 3:23 of the first period, redirecting Nikita Zadorov’s point shot.

“It’s just really special to see our team come together and not take ‘no’ for an answer like we got them early on,” Swayman said. “I think that set the tone for the whole game.”

Coyle pushed the score to 2-0 at 9:57 of the first with a power play goal. After the Bruins prevented several Kraken clearing attempts, the puck was worked under the right circle to Brad Marchand. The Boston captain made a cross-crease pass to Coyle, who turned around Daccord from the left post.

“I was just trying to hang in there, and then your instincts just take over,” Coyle said. “Certain ways you scored before, or something you see or happen to do and you make the right move. But it was a great look from (Marchand), the (power play) move.”
