Pastrnak gave Boston a 3-2 lead at 4:11 of the third period, scoring on a rebound from the left circle after the puck took a big bounce to him off Bobrovsky's pads.
"It's third-period goal, leading goal, so you're definitely thinking that [we're going to win]," Pastrnak said. "We were very close to closing it. … A lot of emotion is running, so that one definitely hurt."
