MONTREAL - Nathan MacKinnon scored goals 13 seconds apart in a three-goal Colorado first period as the Avalanche jumped on a shaky Mike Condon to defeat the Montreal Canadiens 6-1 on Saturday night.

Mikhail Grigorenko, filling in on the top line for the suspended Gabriel Landeskog, scored a goal and set up both of MacKinnon's markers.

Blake Comeau, Matt Duchene and John Mitchell also scored for Colorado (10-9-1), which has won the first three matches on a six-game road trip that next takes them to Toronto on Tuesday night. Duchene's three-point game gave him eight points on the trip.

Brendan Gallagher scored for Montreal (13-3-2), which ended a six-game points streak and suffered a first regulation time loss at home this season.

Rookie goalie Condon, who had remarkable numbers in his first six games in relief of injured Carey Price, finally had a rough start and lost in regulation for the first time. He allowed three goals on eight shots in the first period and four on 11 overall. Dustin Tokarski took over for the third period and stopped 11 of 13 shots.

Montreal tested Reto Berra 40 times.
