Varlamov’s 12th career shutout came one day after prosecutors in Denver filed a misdemeanor assault charge against him because of a complaint by his girlfriend that he attacked her Oct. 30.

McGinn’s fourth goal of the season and first game-winner helped the Avalanche (17-5-0) improve the best start in franchise history. They are 15-0 when they score first.

The Kings, coming off a 2-1 overtime loss to New Jersey on Thursday, were shut out for the first time this season and ended an eight-game stretch in which they recorded at least one point.

Ben Scrivens made 32 saves in his sixth consecutive start for the injured Jonathan Quick. He got a bad break when a rebound trickled into the net off the elbow of teammate Jarret Stoll after Scrivens made the initial save on John Mitchell.

Los Angeles received a 4-minute power play with 77 seconds left in the second period after John Mitchell cut Willie Mitchell with a high stick, but the Kings got only two shots during that stretch and finished 0-for-4 with the man advantage.

Colorado was 0-for-3 on the power play.
