Pastrnak had an assist. It was his second hat trick (Oct. 13 against the Detroit Red Wings) and his third four-point game this season (two goals, two assists Oct. 8 and Oct. 23, each against the Ottawa Senators).
"He's had years where he's come out really hot and kind of tapered off, but the confidence level he has now, the way he's shooting the puck, I don't think it's going to," Marchand said of Pastrnak, who leads the NHL with 15 goals. "He's an incredible player, he has a ton of talent, and he's figuring the game out now, which is making him even more dangerous."
John Tavares scored, and Garret Sparks made 29 saves for the Maple Leafs (11-6-0), who won their first six road games and were on a three-game winning streak.
The Maple Leafs outshot the Bruins 20-6 in the first period. But Boston scored the only goal of the period when Bergeron tipped a Pastrnak pass at 16:12 for a 1-0 lead.
"Well, we didn't score, and then they came out and did," Toronto coach Mike Babcock said. "And obviously then the rest is history. It's an unfortunate thing."
Pastrnak made it 2-0 with a one-timer past Sparks from the left face-off dot at 5:46 of the second period. Defenseman Matt Grzelcyk kept the puck in at the right point and got it to Bergeron, who made a cross-ice pass to Pastrnak.
The Bruins went ahead 3-0 on Pastrnak's second of the night at 10:34. He got behind Maple Leafs defenseman Nikita Zaitsev near the left post, and Marchand passed to him from the right circle.
