NHL Game Summary - Colorado at St. Louis

St. Louis, MO (SportsNetwork.com) - Alexander Steen potted his league-leading 15th and 16th goals of the season to lead an offensive barrage that carried the St. Louis Blues to a 7-3 drubbing of the Colorado Avalanche at Scottrade Center.

The Blues scored five straight times to break a 1-1 tie after one period and hand the Avalanche back-to-back losses for the first time under rookie head coach Patrick Roy -- this one by far the most lopsided of his 18 games behind the bench.

David Backes and Derek Roy each had a goal and two assists in the rout, with T.J. Oshie posting a career-high four helpers for St. Louis. Vladimir Tarasenko added a goal and one assist, while Jaroslav Halak turned aside 21 shots in the Blues' fourth victory in five outings.

St. Louis had little trouble against either Colorado goaltender. Jean- Sebastien Giguere stopped just 18-of-23 chances, while Semyon Varlamov allowed a pair of goals on six shots in a brief relief stint.

Ryan O'Reilly recorded a goal and an assist for the Avalanche, who began the season with six straight road wins prior to Tuesday's setback at Carolina. Nathan MacKinnon and Matt Duchene also scored in defeat.
