The 2015 Lamar Hunt U.S. Open Cup was the 102nd edition of the oldest ongoing competition in American soccer.
The tournament had teams from all three tiers of men's professional soccer, plus teams from the top amateur leagues in the United States. Qualification began in 2014 with USASA regional winners qualifying for 2015. [2] The tournament retained a format that had only two changes from 2014. For the first time, the competition used a fixed bracket system starting with the Round of 16. Teams were grouped geographically into groups of four teams, with each group being paired with another to determine the semifinal pairings. Secondly, a rule was formalized preventing teams from the same ownership group from meeting until the final. [3]
The cash prize amounts were the same as last year, with the champion receiving $250,000 and the runner-up $60,000. Also, the team from each lower division that advanced the furthest received $15,000. [4] The teams that received $15,000 were: (a) PSA Elite an amateur team that advanced to the 4th round where they lost to the LA Galaxy; (b) the Charlotte Independence of the USL advanced to the 5th round where they lost to the Chicago Fire; and (c) New York Cosmos of the NASL which also advanced to the 5th round before losing to the New York Red Bulls.
All United States Division I (MLS), Division II (NASL), & Division III (USL) teams qualify automatically.
