Danny Hoesen struck first in the 6th minute when he received a long pass from Aníbal Godoy and held off both Matt Besler and Botond Barath and punched it in.
Hoesen scored again in the 12th with Jackson Yueill earnign the assist. Another run that broke the offside line of SKC to go in on goal. Tim Melia missed the ball and Hoesen’s shot bounced in off Yohan Croizet.
Sporting KC captain Matt Besler left the game injured after that goal and Abdul Rwatubaye made his first appearance for SKC.
SKC had a chance to close the gap when Gianluca Busio was taken down by Florian Jungwirth in the box. Krisztián Németh stepped up to take but sent the ball high over the bar.
Sporting KC looked a little better the rest of the half but San Jose again punished the visitors at the start of the second half. Shea Salinas found a little space and launched a curling ball just out of Melia’s reach nut just inside to the far post to extend the lead to 3-0 at he 46th minute.
Magnus Eriksson’s deflected shot added insult to injury when it went in at the 61st minute to make it 4-0.
Jungwirth again fouled in the box to give SKC a penalty attempt, this time Felipe Gutiérrez took the shot and buried it in the 66th to salvage some pride and make it 4-1.
