In a hard-fought match at Blackbaud Stadium, the Charleston Battery eliminated the Houston Dynamo 1-0 with a goal in extra time by Stephen Armstrong.
Houston goalkeeper Zach Wells, who bailed out the Dynamo on several occasions, saved the penalty kick by Armstrong in the 106th minute, but Armstrong crashed the net and buried the rebound. It was the fourth win by the Battery over an MLS team in their franchise history (1999 – DC United, 2001 – Metrostars, 2004 – Metrostars).
