OTTAWA -- While Toronto was busy shutting down the Senators' top line Saturday night, Ottawa's second unit picked up the slack.
The line of Fisher, Alex Kovalev and Milan Michalek accounted for all the scoring, with Kovalev scoring the other goal and adding two assists and Michalek finishing with two assists.
"It's nice to see those guys score goals," Senators forward Jason Spezza said. "They've had a lot of chances lately and it's nice to see them get rewarded."
Elliott made his first start in four games.
"Elliott did a great job and made some good saves when he needed to and kept us with that lead," Fisher said. "We're a much better team when we're playing with the lead. Divisional games are really important and that was a big one for us."
Jonas Gustavsson made 25 saves for Toronto. The Maple Leafs have lost three of their last four.
"I don't know if I'd call it frustrating but it's tough for all of us," Gustavsson said. "We had some scoring opportunities but the puck wasn't bouncing for us. We just have to keep working the same way, try to improve myself and the other guys will do their part."
Kovalev opened the scoring late in the first period, collecting a rebound and scoring on the game's first power-play opportunity.
Fisher made it 2-0 at 12:51 of the second, waiting for Gustavsson to commit before slipping a backhander past the goalie. With a minute left in the period, scored on a 2-on-1 break.
"Those were two of the nicest goals you'll see all year probably from our team," Spezza said.
With an average age of 26 years, the Maple Leafs are the youngest team in the NHL. Los Angeles is second at 26.1. ... Toronto defenseman Tomas Kaberle is third on the club's career games played list with 842, two behind Darryl Sittler and 105 back of Bob Pulford.
