Toews tied it 1-1 at 9:25 of the second when he cut behind the defense, collected a pass from Compher and scored five-hole with a backhand.
"We talked about trying to get the middle, and it's harder for their [defense] to play you," Compher said. "They have to kind of make a decision, and it was a great cut by 'Toewser'. Made it really easy on me to make that pass."
Lehkonen put the Avalanche ahead 2-1 at 15:04 while short-handed when he chased down a clearing attempt and fired a snap shot from between the circles past Sandstrom.
"It kind of like slowed down a bit," Lehkonen said. "I don't really know what happened, but I wasn't going on it at first, but then took a fortunate bounce. I was just trying to shoot it quick five-hole."
Compher extended the lead to 3-1 at 11:33 of the third period when he took a pass from Lehkonen at the left face-off circle and fired a wrist shot.
"We were just trying to get the cycle going and support each other, and 'Lehky' makes some really nice play into the middle to me," Compher said. "We didn't want to sit back in the third. We wanted to continue to push, and we did an OK job of that. We knew we had a little more offensively after the first two periods, and it ended up mattering."
