Auston Matthews and Zach Hyman scored in the second period, Frederik Andersen made 32 saves and the Toronto Maple Leafs beat the Boston Bruins 4-1 on Saturday night.
James van Riemsdyk scored in the third for Toronto, which was 0-2-1 in its last three games. Connor Brown added an empty-netter and Andersen improved to 6-0-0 in his career against Boston.
Brad Marchand had the Bruins' goal, and Tuukka Rask stopped 16 shots.
Former Bruins defenceman Matt Hunwick had two assists.
Boston lost to Colorado, then-the NHL's worst team, on Thursday night at TD Garden and followed that by losing to the team that entered as the Eastern Conference's last-place club.
Boston had earned points in 12 of the last 13 meetings against Toronto (9-1-3).
After getting just two shots on goal in the opening period, Toronto moved ahead on Matthews' goal 1:44 into the second. The NHL's No. 1 overall draft pick last summer took a pass from William Nylander and fired a wrist shot over Rask's left shoulder.
Hyman redirected defenceman Jake Gardner's shot from the slot, and the puck dipped and fluttered by Rask to make it 2-0 with 4:46 remaining in the period.
Marchand took advantage of a turnover behind Toronto's net, slicing it to 2-1 with 1:21 left in the second. Andersen misplayed a clearing attempt, firing the puck off a player where it dropped next to the rear boards. He had a second chance to clear or cover it, but Marchand beat him to it, circled and put in his own rebound.
The Bruins had the best chance in the first period when David Pastrnak's one-timer from the left point caromed off the left post early into the game.
Tyler Bozak's shot was tipped in by van Riemsdyk midway into the third.
