ST. LOUIS — David Perron scored a power-play goal early in the third period to lead the St. Louis Blues to a 4-2 victory over the Vancouver Canucks on Thursday night.
Perron and T.J. Oshie each had a goal and an assist for the Blues, who are 8-2-1 in their last 11 games as they try to get into the Western Conference playoffs.
Chris Mason stopped 21 shots for his first career victory over the Canucks in eight appearances. Mason, who played in his 25th straight game, improved to 21-20-6 after a 3-13 start.
David Backes added his 25th goal of the season for St. Louis, and Andy McDonald put the game away with a 5-on-3 tally with 34 seconds left.

Perron converted from close range off a pass from Keith Tkachuk 2:58 into the third period. Perron poked the puck into the lower left corner of the net for his 13th goal.
Backes’ short-handed goal gave the Blues a 2-1 lead midway through the second. Oshie had tied the game three minutes earlier by faking goalie Roberto Luongo to the ice and sliding the pick into the net. Perron sent Oshie in alone with a perfect pass.
Burrows tied it 2-2 with his 25th goal midway through the second period. Burrows picked up a loose puck during a scramble in front and muscled it past Mason.
Vancouver jumped in front 1-0 on a goal by Pyatt 4:15 in. Pyatt wristed a shot between Mason’s pads for his 10th goal.
