FC Dallas remain pointless on their travels this season, following a narrow 1-0 loss to Vancouver Whitecaps at BC Place.
Camilo Sanvezzo scored the only goal of the game after 11 minutes. Following good work from Lee Young-Pyo, the Brazilian forward cut in from the right wing and hit a low curling left-footed shot from 18 yards that nestled in the far corner.
In a game where chances were few and far between, Brek Shea had the best opportunity to level for the visitors but the giant winger's low shot from 9 yards was brilliantly saved by Joe Cannon.
Dallas had lost their two previous away games to Sporting Kansas City and D.C. United.
