Shortly after Swayman made his second of two key early stops on a Nicholas Robertson point-blank rebound, Beecher buried Jesper Boqvist's two-on-one pass to the left circle at 2:26 of the first period.

Boston could have extended its lead if Charlie McAvoy and Pavel Zacha hadn't hit posts within a 2:05 span in the first period.

The Bruins began their second-period scoring onslaught at 5:47 as Carlo buried a drive from the top of the right circle off DeBrusk's feed.

DeBrusk scored on the last two of Boston's three power plays in the middle frame to increase the lead to 4-0, including a snapshot from the right circle at 15:02.

The third goal on Boston's nine second-period shots occurred when DeBrusk redirected Brad Marchand's centering pass off Samsonov and over the goal line.

The Maple Leafs ended the shutout in the third. At 1:39, Kampf glided down the slot and buried Connor Dewar's slick backhand feed.

Frederic's empty-net goal with 2:08 left sealed the win.
