Arvedson's goals help sink Blues

ST. LOUIS -- Magnus Arvedson scored two goals for the second straight game and the Vancouver Canucks extended their winning streak to four Thursday night with a 4-2 victory against the slumping St. Louis Blues.

Daniel Sedin had a goal and two assists for Vancouver. Arvedson and Markus Naslund sparked the Canucks' four-goal third period, scoring in a span of 1:42 to end Chris Osgood's shutout bid and put Vancouver ahead.

Arvedson scored his eighth goal of the season, and fourth in three games since returning from a six-game absence due to a herniated disc, for a two-goal gap midway through the third.

Mark Rycroft and Keith Tkachuk scored for the Blues, who are 0-4-1 in their last five games and 5-11-5 in their last 21. They've totaled 10 goals in their last seven games, and lost when leading after two periods for only the second time all season, falling to 19-2-2.

Osgood is 1-9-4 with two no-decisions since Dec. 18.

The Blues played without forward Pavol Demitra, who missed the game with a hip pointer.
