Frederik Andersen made 26 saves in his fourth career shutout, Sami Vatanen scored on a power play in the second period and the Anaheim Ducks beat the Buffalo Sabres 1-0 on Wednesday night for their season-best sixth straight victory.

The resurgent Ducks climbed within two points of the Pacific Division-leading Los Angeles Kings. Anaheim is 20-4-2 since losing back-to-back games road games against the Islanders and Rangers on Dec. 21-22.

Robin Lehner made 28 saves for the Sabres, who were shut out for the fifth time. Andersen is 4-0-0 with a 1.00 goals-against average in four career starts against Buffalo. This was his first shutout of the season.

The Ducks had scored at least five goals in a franchise-record four consecutive games coming into this one but failed to get a shot on net during the final 10:38 of a scoreless first period.
