John Klingberg scored 35 seconds into overtime, Antti Niemi stopped a pivotal penalty shot in the third period and the Dallas Stars snapped an eight-game skid against Colorado, beating the Avalanche 4-3 on Thursday night.
Klingberg beat Calvin Pickard with a slap shot on a breakaway just moments into overtime.
The winner came after Jason Demers scored a power-play goal to tie it with 8:40 remaining in regulation. Before that, Niemi turned aside Nathan MacKinnon's penalty shot.
Jason Spezza and Ales Hemsky each had a goal for the Stars, who won in Denver for the first time since Feb. 4, 2013.
Nick Holden, Blake Comeau and Carl Soderberg scored for Colorado.
