Cam Atkinson scored the shootout winner and Steve Mason made 28 saves after coming in for an injured Curtis Sanford as the Columbus Blue Jackets beat the Calgary Flames 2-1 on Sunday night.
Nikita Nikitin scored for Columbus, which was playing on back-to-back nights. The Blue Jackets lost 4-3 Saturday night in Vancouver.
Matt Stajan scored for Calgary (34-26-13), which snapped a four-game home winning streak.
It was a costly weekend for Calgary's playoff aspirations in the congested Western Conference. The Flames remained in 11th place after dropping two straight, including Friday's 3-1 loss to the Edmonton Oilers.
Sanford was hurt early in the first period and did not return.
