T.J. Oshie assisted on four goals (his first career four-point game), David Backes and Derek Roy each had a goal and two assists, Alexander Steen scored his League-leading 15th and 16th goals of the season, and Vladimir Tarasenko and Alex Pietrangelo each had two points for the Blues (12-2-3), who beat the Colorado Avalanche 7-4 Thursday night at Scottrade Center.

The Blues did it with special teams, going 3-for-4 with the man advantage, and with their top unit of Oshie, Backes and Steen collecting nine points. Jaroslav Halak stopped 21 shots, helping St. Louis defeat Colorado for the fifth straight time at home.

Colorado is 14-4 and in second place in the Western Conference, just behind Chicago, but have lost two straight for the first time this season. St. Louis is one point behind the Avs.
