Colorado outshot Toronto 10-4 in the second period, though Georgiev came up with difficult saves at 15:06 on a one-timer from Rielly below the right hash marks in the slot and at 18:13 on Calle Jarnkrok at the top of the goal crease.
"We talked about it as a team, just playing hard defensively," Avalanche defenseman Bowen Byram said. "When we went through that stretch where we lost a few games in a row (three straight from March 1-5), we weren't too happy with what we were doing on the defensive side of the puck, so we've just been trying to key in on it lately.
"They're a really good rush team, so [it's] just our defense having tight gaps, pinching down the walls if we can. Our forwards did a great job of tracking back over top of the puck and forechecking as well. Those are keys every night, but when you are playing some of the best players in the world, you have to make sure those details are on."
Colorado outshot Toronto 4-0 in overtime.
"It's just commitment and hard work and paying attention to the details," Bednar said. "When we play with that type of commitment and dedication to the checking side of things, we're pretty good at it.
"I feel like some nights we are as good as we want to be, and it seems like recently we've wanted to win these hockey games. We know they're important. Winning the division isn't the be-all, end-all, but certainly to have short-term goals like that and chase down the teams in front of us, it's part of playing with a little pressure, even if it is self-induced."
Samsonov, who backed up Matt Murray the previous two games and had not played since making 30 saves in a 4-3 win at the New Jersey Devils on March 7, stopped Nichushkin on a short-handed breakaway at 3:29 of the second.
"I thought he was locked in," Maple Leafs coach Sheldon Keefe said. "I don't think we gave up a ton in terms of high-quality chances, a lot of stuff coming from the points and the perimeter, but anything we did give up in the slot or whatever it might have been, he was set. He looked really athletic and dynamic with some of the saves he made with his hands. I thought he was excellent."
