Cordell Cato and Chris Wondolowski both scored twice as the San Jose Earthquakes ended Sporting Kansas City's unbeaten home run.
The San Jose Earthquakes continued their resurgence Wednesday, becoming the first MLS side to win at Sporting Kansas City this season.
A stunning opening half-hour from the Earthquakes set up their 5-0 victory, with Cordell Cato and Chris Wondolowski both notching doubles.
A dreadful match for Sporting got even worse in the 71st minute as Benny Feilhaber was shown a straight red card for denying a clear goal-scoring opportunity, as Peter Vermes' men saw their unbeaten run at home end after 12 games.
