"We needed that goal. We needed a big way to take the lead back, calm things down a little bit," Bednar said. "I thought that's a big moment in the game. [Our players] are under pressure. They know we didn't play that well to start the period."
Keller responded to tie it 3-3 at 15:28 with a spinning shot from the right face-off circle.
"He just surprised the goalie on that one," Tourigny said. "Sometimes [goals occur] not always because it's a great player or it's a clever play or whatever, it's just a hardworking play."
The Avalanche were outshot 16-9 in the third period and overtime.
"[Georgiev] was fantastic in the shootout," Bednar said. "That's the way to bounce back and be resilient, stay mentally tough. I liked the way he responded."
Rantanen gave Colorado a 1-0 lead at 9:30 of the second period two seconds after a power play expired. After intercepting a pass up the boards by Ingram, Rantanen scored on a wraparound as the goalie tried to scramble back into position.
Bowen Byram pushed it to 2-0 at 10:46. Logan O'Connor's initial shot was saved by Ingram, but the rebound kicked off the skate of Jack McBain and deflected back into the crease, where Byram knocked it in.
