The 19-year-old rookie beat Jonas Hiller at 1:52 of overtime to lift the Avs to a thrilling 3-2 victory against the Anaheim Ducks at the Pepsi Center. The win moved Colorado (37-30-4) into eighth place in the West, two points ahead of the Calgary Flames. Calgary was idle Monday night and fell from eighth place to 10th as the San Jose Sharks also moved ahead of the Flames with a win at Edmonton.
"It was one of those games where I didn't know if I was going to be able to contribute out there," Landeskog said. "I kind of hung in there. I thought I was holding our line down a little bit. I was struggling most of the game, but those are the kind of games where you have to take it one shift at a time, take short shifts and kind of let my teammates do the job. To get an opportunity in OT, I just wanted to get it on net for it to go in."
