DENVER (AP) -- Semyon Varlamov was sharp in making 35 saves, and Jamie McGinn scored two goals, leading Colorado to a 6-1 win over the Anaheim Ducks on Wednesday night in Patrick Roy's coaching debut with the Avalanche.
Ryan O'Reilly, John Mitchell, Matt Duchene and Steve Downie added goals for the Avalanche, who improved to 19-8-7 on opening night. Top pick Nathan MacKinnon set up both of McGinn's goals with no-look passes. Alex Tanguay, back with Colorado for the first time since the 2005-06 season, had three assists.
Varlamov stuffed the Ducks all evening but lost his bid for a shutout in the closing seconds when Jakob Silfverberg slipped a shot by him.
Viktor Fasth struggled for Anaheim, allowing three goals in the second period.
Things got heated after the final horn, with some players getting into a skirmish near the benches. Even Roy got into the act as he jawed from behind the glass.
