Walker put Colorado ahead 1-0 at 10:39 of the second period. He took a lead pass from Lehkonen and scored blocker side from the right circle on a 2-on-1.
“I think it was just a team win. Fast transition on both sides of the puck led to some odd-man rushes and some good offense,” Walker said. “I think there was definitely some waves to the game there."
Zach Hyman appeared to tie it at 2:05 of the third period, but a video review determined that he kicked the puck into the net.
Foegele did tie it 1-1 at 5:46, tipping in a point shot by Evan Bouchard.
Carrick gave Edmonton a 2-1 lead at 11:48, getting inside position and scoring from in front. It was his first goal with the Oilers since being acquired in a trade with the Anaheim Ducks on March 6.
“It was awesome. A Saturday night 'Hockey Night in Canada' and all that. It's pretty special, being a Canadian kid,” Carrick said. “Two really good, fast teams going at it. We're heading down the stretch here where we're getting close to that time of year, a fun time of year.
“There's under 20 games here to really build chemistry, no matter who's in the lineup and what the lines are. Figure out your linemates and how they play. You want to be able to roll four lines throughout the playoffs.”
