David Bulow scored off a corner kick in the 31st minute and the Richmond Kickers' defense did the rest in a 1-0 upset of the Los Angeles Galaxy in their U.S. Open Cup match on Tuesday.
With the victory over the Major League Soccer's Galaxy, the defending second division champion Kickers advance to the next round to face the winner of the Chicago Fire and Carolina Railhawks match.
The Galaxy, which awaits the much-anticipated arrival of David Beckham later this week, has struggled so far this season in MLS play, and was heavily favored over the Kickers in the contest at Richmond, Va.
In another Open Cup loss for an MLS team, the Charleston Battery eliminated the Houston Dynamo 1-0 on Steven Armstrong's rebound of his own penalty kick in extra time.
Houston goalie Zach Wells blocked Armstrong's kick from the spot, but Armstrong charged forward to put the ball into the net.
The Battery will face FC Dallas in the quarterfinals.
Taylor Twellman scored twice, the second time for the go-ahead goal in the 90th minute, and the New England Revolution beat the Rochester Rhinos 4-2 in their match.
Steve Ralston added an insurance goal for the Revolution on a penalty kick in stoppage time.
New England next faces the winner of D.C. United and Harrisburg City Islanders.
Jose Cancela and Herculez Gomez each had a goal and an assist in the Colorado Rapids' 3-1 win over the California Victory.
