Carl Soderberg and Torey Krug scored second-period power-play goals, and the Boston Bruins defeated the Maple Leafs, 5-2, in Toronto on Sunday.
The Bruins were coming off a Saturday night win over Pittsburgh in which Shawn Thornton had a takedown of Brooks Orpik. The Bruins were without the suspended Thornton as well as Loui Eriksson and Chris Kelly, who were both injured in the game.
The Leafs controlled the play early on and led by 1-0 after the first on a goal by Peter Holland.
But the Bruins had a three-goal outburst in the second period, including a pair of power-play goals in a 93-second stretch.
Jason Chimera, Steve Oleksy, and Mikhail Grabovski scored second-period goals to power the Washington Capitals to a 4-1 win over the host New York Rangers.
New York, beaten at home in overtime by New Jersey on Saturday, has lost three of five.
Patrick Sharp had a goal and two assists, and the host Chicago Blackhawks scored a season-high three times on the power play in a 6-2 win over the Florida Panthers.
The Blackhawks used their potent offense to win after starting goalie Corey Crawford left in the first period because of a lower-body injury.
Josh Harding made 37 saves in another strong home outing, and the host Minnesota Wild beat the San Jose Sharks, 3-1, despite recording only 13 shots.
