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.

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.
