CANUCKS 1, BLUES 0
VANCOUVER, British Columbia (AP) — Jannik Hansen scored the game's only goal and Eddie Lack made 20 saves for his third shutout of the season as the Vancouver Canucks blanked the St. Louis Blues.
The Canucks ended their losing streak at seven games while moving into sole possession of eighth place in the Western Conference. The Blues dropped their third straight decision to Vancouver this season.
Hansen broke a scoreless deadlock at 11:13 of the third period. He took a backhand stretch pass from Tom Sestito from deep in the Vancouver zone just past centre ice, raced in on a breakaway and beat Jaroslav Halak with a high shot.
KINGS 6, AVALANCHE 4
DENVER (AP) — Anze Kopitar had two goals, including the decisive score in the third period, and the Los Angeles Kings rallied to beat the Colorado Avalanche.
Kopitar's second goal of the night and 19th of the season put the Kings, who trailed by two goals midway through the second period, back in front.
The Kings were on the power play when Jeff Carter, in the middle of a scramble in front of the net, swung at a loose puck, sending it straight up in the air. When the puck hit the ice, Kopitar got his stick on it and sent it into the net past goalie Jean-Sebastian Giguere at 3:13 of the third period.
Justin Williams added an empty-net goal with 11 seconds left to round out the scoring.Suggest a correction
