had two assists, and Anton Forsberg made 31 saves for the Senators (22-23-3), who have won two in a row, including a 2-1 victory against the New York Islanders on Wednesday. Ottawa scored the final four goals of the game.
The Senators host the Montreal Canadiens on Saturday.
"I just thought we played with a lot of confidence," coach D.J. Smith said. "I thought we did against the Islanders and it carried over tonight. Just made more plays, carried the puck, just a lot of good efforts."
Joey Anderson and William Nylander scored, and Ilya Samsonov made 28 saves for the Maple Leafs (30-12-8), who were 4-0-1 in their previous five and are 2-1-0 through three games of a five-game homestand. Samsonov fell to 14-1-1 at home this season.
"We played good in the first period, and then we just fell away from that," Nylander said. "We didn't win our battles and let them take over the game.
"For sure I think we took our foot off the gas. I mean, that's unacceptable. So, we've got to work on that. That's something we've got to improve on."
