Toronto outshot Ottawa 14-4 in the second period before the Senators responded by outshooting the Maple Leafs 16-5 in the third.
“I think we had a lot of grade-A chances (in the second),” Toronto forward William Nylander said. “Ullmark played very well as well. You have to give it to him. If he didn’t play that well, we could have had a couple (more) goals in the first and second periods.”
Chabot put the Senators up 1-0 at 18:52 of the first period when he put in a rebound at the side of the net after Shane Pinto’s shot was deflected by Giroux in the slot.
“It was awesome, I’m not going to lie,” said Chabot, who was named captain Tuesday. “I’ve never been the guy to make it about myself, but scoring the first one of the game was pretty cool. My parents were here too in the building. It’s been a special last couple days, just happy we got the first win of the year.”
The Maple Leafs tied it 1-1 at 33 seconds of the second period when Matthews scored in the slot by deflecting Morgan Rielly’s shot from the blue line.
Marchenko scored his first goal with the Maple Leafs to put them up 2-1 on the power play at 7:06 of the second period. Darren Raddysh sent a pass from the point to Marchenko at the right side of the net, where he then went to his backhand, stepped toward the slot and shot past Ullmark’s blocker.
“It’s an amazing feeling,” said Marchenko, who was traded from the Columbus Blue Jackets on Monday. “I am happy so much but I’d be most happy if we’d win the game tonight. It’s an unbelievable feeling, how fans support me too, my teammates on the ice, but still we need to find a way to win these games.”
Amadio tied it 2-2 at 12:40. Tim Stutzle lifted a pass over a sprawling Rielly on a 2-on-1 to Amadio, who redirected it past Bobrovsky at the side of the net.
