The Chicago Fire won their 3rd Open Cup title with a 1–0 victory over the MetroStars in the final at Giants Stadium, East Rutherford, New Jersey. Chicago missed out on a domestic treble (with the Supporters' Shield) when the Fire lost MLS Cup 2003.
The Open Cup tournament was dominated by MLS squads, as only two non-MLS teams reached the quarterfinals. The Pro Select League's Wilmington Hammerheads were the story of the tournament, winning four straight games to reach the quarterfinals, including a 4-1 thrashing of MLS side Dallas Burn. The A-League's Seattle Sounders were the only other minor-league team to beat an MLS team, winning 1–0 over San Jose.
