Sebastian Fernandez was the hero as the Vancouver Whitecaps stunned Western Conference leaders the Seattle Sounders 1-0 in MLS on Saturday.
Fernandez opened the scoring in the 12th minute - unleashing from distance - and it proved to be the match-winner at BC Place Stadium in Vancouver.
The Uruguay striker received a pass from Whitecaps team-mate Pedro Morales and the 24-year-old fired a 30-yard strike past Sounders goalkeeper Stefan Frei.
The Whitecaps had chances to double their advantage, while the Sounders had opportunities of their own but it was the Vancouver outfit that emerged triumphant on home soil - ending Seattle's six-game unbeaten streak.
Seattle remain atop the standings in the West after 17 games, seven points clear of Real Salt Lake and 10 ahead of the fifth-placed Whitecaps, who have a game in hand.
