Pastrnak did just that, admitting that he only picked up the pass from Marchand at the last second. His 15th goal of the season extended his league-leading points streak to nine games (5-6-11).
"I didn't even see Marchy," said Pastrnak, who was playing in his 200th career game. "Last time I saw him he was coming down the wall. I thought he was going to shoot it. I saw the puck real last second. It was not an easy shot; it was coming pretty hot. But I got it on the ice and had an empty net. I'm surprised I even hit that puck."
Boston started the extra session with Patrice Bergeron, Torey Krug, and Marchand - Cassidy's preferred overtime trio. They wasted little time ending it.
Bergeron helped Marchand dig the puck off the wall in the Bruins' end, before Marchand quickly moved it to Krug (two assists) and started a 2-on-1 through the neutral zone. With Mike Green closing on Krug, the blue liner sauced a backhand to Marchand in open ice.
Marchand broke in all alone on Jimmy Howard and shook off a late attempt by Green to break up the play, roofing a backhander over the sprawling Howard for the winner just 35 ticks into extra time.
"They played a really good defensive game. They didn't give us a whole lot," said Marchand. "They play really tight, almost a man-on-man over the whole ice; they really collapse in the D-zone. If you don't take care of pucks, which we didn't do a good job of early on you're not going to get much and they worked hard.
"They out-battled us early on. Luckily we were able to bounce back."
