Mikko Rantanen scored twice in the third period as the Colorado Avalanche won 6-3 in Tuesday's Game 5 to eliminate the Winnipeg Jets.
The Avalanche will play either the Dallas Stars or Vegas Golden Knights in the second round. Colorado is the first lower seed to advance in the Stanley Cup Playoffs this year.
"We came in really humble this year," star forward Nathan MacKinnon told Sportsnet's Scott Oake. "We were really bad down the stretch. We got beat by these guys 7-0 at home, and for whatever reason, it just kind of woke us up that we really needed to fix some things. Right now, we've got every guy playing really hard and playing the right way."
