Cale Makar and Martin Necas each had a goal and an assist, and Nathan MacKinnon had three assists for the Avalanche (33-4-8), who have lost three of their past five games (2-2-1). Miner made 28 saves.
It was Colorado's first loss at home since Oct. 23, ending a 17-game winning streak. The Avalanche are 19-0-3 overall at Ball Arena this season.
“Evenly played game, probably,” Colorado coach Jared Bednar said. “Even first, they beat us in the second. I thought we were better in the third, but you got to play a full 60 if you want to win. It's just that simple. So, we weren't quite there tonight.”
Cowan gave Toronto a 1-0 lead at 11:15 of the first period when his backdoor pass for McMann from the left corner deflected inside the right post off the skate of Brent Burns.
“It was a pretty fun game. That's a good team over there, and we stuck to our game and [were] right there with them the whole time,” Woll said. “Just an exciting game all the way through, down to the last shot. 'Willy' coming in clutch again is huge for us. So, yeah, big win for us.”
Makar tied it 1-1 at 16:12. Necas spun away from Jake McCabe, who fell down, above the outside edge of the left circle before sending a cross-ice pass to Makar, who roofed a shot over Woll's left shoulder from the right circle.
“That was great pass by him. I think that's when we're at our best dynamic in the O-zone,” Makar said. “[Burns] and I are kind of rolling around up top and then still being responsible, but then finding those seams and opening them up. So, it was a great pass by Marty, and he started it for us tonight.”
