(Reuters) - Rookie goaltender Jake Allen shook off the concession of a game-tying goal in the final minutes of regulation to make a string of key stops as the St Louis Blues sealed a 4-3 shootout win over the Vancouver Canucks on Sunday.

Vancouver's Mason Raymond forced overtime when he beat Allen with just 1:47 left in the third period to make 3-3, but the first-year netminder refused to remain despondent.

Allen made five saves in overtime, finishing with 28 overall, and blocked Vancouver's two shootout attempts to ensure St Louis (9-5-1) won for the third time in a row and he remained unbeaten in his first three starts.

Ryan Kesler scored the first goal of the game, in only his second contest of the season, and Henrik Sedin added another to give Vancouver a 2-1 first period lead after T.J. Oshie had equalised for the visitors.

Andy McDonald netted an equaliser in the second and Patrik Berglund's deflection in the third put St Louis 3-2 ahead before Raymond completed the scoring.

The Canucks (8-3-3) have now lost two straight since ending a six-game winning streak but still lead the Northwest Division by three points over Minnesota.
