Zacha had an assist and two shots on net in Thursday's 6-4 win over Montreal.
The Bruins top line combined for the fourth goal, as the forechecking Zacha and Elias Lindholm each won puck battles that led to David Pastrnak's tally. Zacha had the primary assist, spinning away from David Savard behind the net and finding an impossibly open Pastrnak in the slot. It was the second point in as many games for Zacha, who scored in the season-opening loss to Florida.
