Frederic gave the Bruins a 1-0 lead at 19:08 of the first, shooting a backhand over the shoulder of Lyon on a breakaway. Lyon was shaken up after a collision with Frederic but remained in the game after getting attention from the training staff.
“[Pastrnak] hit a pretty good 60-degree wedge to me,” Frederic said. “I was a little slow getting after it, so all I had was the backhand. I was lucky to get it up and over his shoulder.”
Frederic made it 2-0 at 4:25 of the second period with a wrist shot from the right wing after skating past Dylan Larkin.
“I think he’s playing faster, and he’s underrated as a great skater,” Montgomery said. “He’s driving pucks consistently instead of delaying, which he did a lot, and he’s opening up space for himself.”
Walman made it 2-1 at 13:01 with his third goal in two games.
Chiarot tied the game 2-2 with a shot from the slot at 16:42.
Charlie Coyle gave Boston a 3-2 lead at 3:52 of the third period, shooting a one-timer past Lyon from the slot off a pass by McAvoy.
“That was disappointing,” Lalonde said. “They had one chance in the third period on a missed face-off assignment, and it ended up in the back of our net.”
