The squad was surprised by Italy in the team round semifinal, and was forced to shoot a tie-breaker against Russia in the bronze medal match to claim their medal. Karen Scavotto faced Denise Parker in the first round, guaranteeing an elimination for one of the American women.

The medals were returned to all athletes, except Young, on July 22, 2005 when the Court of Arbitration for Sport ruled that the IAAF and IOC rules in 2000 did not call for the disqualification of an entire team due to the doping offenses of one athlete. Later, the medals were stripped again on August 2, 2008, after Pettigrew admitted to also using performance enhancing drugs. Pettigrew's individual results were also nullified.
