TORONTO -- Mitchell Marner scored with 1:06 remaining in overtime to give the Toronto Maple Leafs a 2-1 win against the Ottawa Senators at Scotiabank Arena on Saturday.
Marner won it with a one-timer on the power play after receiving a pass in the high slot from William Nylander.
"I don't think anyone really thinks I'm going to shoot that," Marner said. "The first passes I got, I looked at the net and saw a little bit of a lane and then the third pass I got I decided to try to get it to the net with John Tavares in front. Luckily it went in."

Jason Spezza also scored, and Michael Hutchinson made 24 saves for the Maple Leafs (28-17-7), who have won three in a row.
"I thought we stayed with it," Toronto coach Sheldon Keefe said. "We knew it was going to be a hard game and it was, they played extremely hard and credit to them for the plan they put in place. On back-to-back games for them, it was clear how important this game was to them, but it was important to us as well."
Mark Borowiecki scored, and Craig Anderson made 34 saves for the Senators (18-24-10), who were coming off a 5-3 loss to the Washington Capitals on Friday.
Borowiecki gave Ottawa a 1-0 lead at 6:08 of the second period when his slap shot from the left boards beat Hutchinson blocker side through a screen.
"It was an interesting game, a little bit different style than what we're typically used to," Borowiecki said. "They play an interesting way, really try to hog the puck out there and hang on to it so you get some different looks, but I thought we adapted pretty well and played them tight."

Hutchinson made a number of key stops to keep the Maple Leafs to within one goal, including a blocker save on Chris Tierney on a 2-on-1 at 8:01, a blocker save on Jean-Gabriel Pageau at 8:54, and a save on Brady Tkachuk on a partial breakaway at 9:02.
"Those three saves in the second period, they came one after the other," Hutchison said. "At that point in the game, I think those were three big saves looking back on it now that gave us a chance to win the game tonight."
Spezza tied it 1-1 at 10:41 of the second with a slap shot from the top of the right circle on the power play following a face-off win by Alexander Kerfoot.
"I felt good. It was a tight game, so it was good to make some plays, but it was good to contribute," Spezza said. "My whole life I've been told I have to shoot the puck more, so I just took what was there. They shaded off me there and I was able to get a good look after [Rasmus] Sandin did a good job getting it over to me quick."
Maple Leafs forward Kasperi Kapanen was a healthy scratch for the first time this season because of an issue pertaining to internal accountability, Keefe said.

They said it
"It was a pretty exciting game to be a part of. I think the fans enjoyed it and there was a lot of energy in the building. That's a team you can't trade chances with, they've got too much firepower and I thought we did a good job though limiting the amount of chances we gave up. They gave up some chances and we just weren't able to capitalize on it." -- Senators goalie Craig Anderson
"He's been huge for us. Last year he was huge for us when he was in that net as well. I mean, everyone goes through slumps and games that they don't like. It happens in this League, but I think now he's got his confidence back, his swagger back. He gives our whole team confidence when we see him making some of those big saves. He's been great for us and it's great seeing him have his swagger back." -- Maple Leafs forward Mitchell Marner on Michael Hutchinson, who has won four straight starts
