Mitch Marner scored twice, including a second-period penalty shot, as the Toronto Maple Leafs drew first blood with a 4-1 win over the Boston Bruins in Game 1 of their NHL Stanley Cup Playoffs first-round series Thursday night at TD Garden in Boston.

Patrice Bergeron gave the Bruins a 1-0 lead with a power-play goal 9:31 into the first period, assisted by Brad Marchand and Torey Krug, but Marner got the Leafs even at 16:44 with a goal from Jake Muzzin and John Tavares.

Marner’s penalty shot came while Toronto was shorthanded. Boston’s Jake DeBrusk hauled Marner down on a breakaway scoring chance, and on the penalty shot Marner deked Bruins goalie Tuukka Rask and tucked the puck into the corner of the net.

Willaim Nylander added to Toronto’s lead with a goal at 18:25 assisted by Nazem Kadri and Patrick Marleau. Tavares added an empty-net goal.

Frederik Andersen made 37 saves for the Leafs. Rask stopped 29 for Boston.

Game 2 is Saturday night at 8 at TD Garden.
