Connor Brown and Cody Goloubef scored for the Senators (19-28-11), who fell to 1-5-2 in their last eight games. Marcus Hogberg was pulled after giving up three goals on 16 shots. Craig Anderson stopped all 14 he faced.

Zach Hyman had a great opportunity to restore the two-goal lead as he took advantage of a Senators giveaway and broke in alone short-handed, but Anderson made a great glove save to keep Ottawa within reach.

The Senators got on the board at the 16-minute mark as Chris Tierney made a nice pass out front to Vladislav Namestnikov, who fed Brown for his 11th of the season into an open net. With his 36th point, Brown, a former member of the Maple Leafs, tied his career high.

While games against Toronto have always brought Maple Leafs fans to Canadian Tire Centre, on this night it was hard to find a Senators jersey throughout entire sections of the building. The crowd of 18,544 was the biggest of the season for Ottawa.

The Senators cut it to 3-2 midway through the third period when Goloubef scored his first goal since Nov. 17, 2015.

Zach Hyman had a great opportunity to restore the two-goal lead as he took advantage of a Senators giveaway and broke in alone short-handed, but Anderson made a great glove save to keep Ottawa within reach.

Marner sealed it on an empty-net goal with just more than a minute remaining. He flipped the puck into the net from deep in his own zone, launching it over the Senators defense.

Toronto opened a three-goal lead in the second. Muzzin sent a wrist shot past a screened Hogberg, who had no chance at the puck. Ten minutes later, Nylander tipped John Tavares’ shot past Hogberg to make it 3-0 and end the Ottawa goalie's night.

Toronto came out of the first with a 1-0 lead after Matthews was able to squeeze a shot through Hogberg, a goal the rookie would surely want back.

NOTES: With Mark Borowiecki sidelined by an ankle injury, Thomas Chabot was given the "A". ... Mikkel Boedker was the lone healthy scratch for the Senators. ... Toronto canceled practice Friday because of a flu bug making its way around the team.
