Shaka Bangura scored seconds after play resumed following a long lightning delay, sparking the minor-league Richmond Kickers to a 2-0 upset of Sporting Kansas City in the quarterfinals of the U.S. Open Cup on Tuesday night.

It was Kansas City's first loss in seven outings in its new home, the $200 million Livestrong Sporting Park.

David Bulow assisted on Bangura's 66th-minute winner and added an insurance goal on a penalty kick in the 83rd. Kickers goalkeeper Ronnie Pascale made five saves, including several down the stretch as Sporting tried furiously to get back in the game.

Richmond, which plays in USL Pro - the third tier of professional soccer in the U.S. - will face the Chicago Fire in the semifinals on Aug. 30. The Kickers have beaten two MLS teams already in the tournament, including a 2-1 victory over Columbus in the third round that put them in the quarterfinals.

The game was scoreless when lightning forced an 82-minute delay in the 65th minute. Moments after play resumed, Bulow crossed to a streaking Bangura, who calmly put the ball past keeper Erick Kronberg.

Bulow's penalty kick came after defender Aurelien Collin brought down Jamal Wallace in the area in the 82nd minute.
