Frederic tied it 1-1 at 13:54 after Jesper Boqvist’s forecheck behind the net caused the puck to fall to Frederic in front.
Frederic nearly put the Bruins ahead when he had a prime netfront chance at 12:28 of the third period, but Woll held strong with his outstretched right pad as Frederic went backhand to forehand.
“It’s pretty special. I mean, I’m having the time of my life out there,” said Woll, who played for Boston College from 2016-2019. “[TD Garden is] a place I’ve played a lot of big games, and to come in here and play the Bruins in an elimination game is pretty special. So I thought from the drop of the puck, our team had a different level of urgency and it made me confident back there.”
Later in the third, Max Domi took the puck away from Bruins forward Charlie Coyle to create a 2-on-1 rush with Tyler Bertuzzi, but Swayman swallowed up Bertuzzi’s one-timer from the right circle at 14:55 to keep it tied.
Woll made a pad save on Coyle’s shot from the low slot 43 seconds into overtime.
“That’s just the way it plays out sometimes,” Bruins captain Brad Marchand said. “The hardest [win] to get is that last one, and you know, like I said, they came and they left it all out there. That’s just -- we need to be better. That’s all it is.”
NOTES: Knies (21 years, 196 days) became the sixth-youngest player in Maple Leafs history to score a playoff overtime goal. … Woll earned his second win in a potential series elimination game, which tied Gord McRae, Felix Potvin and John Ross Roach for the most by a rookie goaltender in Toronto history. Woll got the win in Game 4 of the second round last season, a 2-1 victory against the Florida Panthers, who won the series in five games. … Bruins forward Justin Brazeau had five hits and played 10:03 in his NHL playoff debut.
