Gabriel Landeskog scored twice, including a power-play goal at 4:27 of overtime to help the Colorado Avalanche extend their winning streak to four with a 3-2 victory over the Columbus Blue Jackets on Tuesday night.
Rookie scoring leader Nathan MacKinnon, centering the top line with Matt Duchene expected to miss a month with a knee injury, assisted on both of Landeskog's scores.
Semyon Varlamov stopped 26 shots -- including a prime chance by Blake Comeau late in regulation to pick up his league-leading 38th win.
With 102 points, Colorado moved three ahead of Chicago for second place in the Central Division.
Cam Atkinson and Comeau scored in the second period for Columbus, which is hanging on to the second wild-card spot and eighth playoff seed in the Eastern Conference.
