Anderson helps Senators snap skid, top Leafs 5-2
Sergei Gonchar, Zack Smith and Milan Michalek added goals for Ottawa, which continues its six-game road trip with a swing through Western Canada next week
Tyler Bozak and Joffrey Lupul scored for Toronto.
Anderson's play has been a concern for Ottawa coach Paul MacLean, who pulled the veteran just two minutes into a loss to the Buffalo Sabres on Friday night. Anderson looked sharp against the Maple Leafs and closed the door in the third period with the home team pressing.
