# 2010 U.S. Open Cup

The 2010 Lamar Hunt U.S. Open Cup was the 97th edition of the USSF's annual national soccer championship, running from June through early October.
The tournament proper featured teams from the top five levels of the American Soccer Pyramid. These five levels, namely Major League Soccer, the USSF D-2 Pro League, the United Soccer Leagues (Second Division and Premier Development League), and the United States Adult Soccer Association, each have their own separate qualification process to trim their ranks down to their final eight team delegations in the months leading up to the start of the tournament proper. The eight MLS clubs received byes into the third round, while the remaining 32 teams played in the first two rounds, with brackets influenced by geography.
The final took place on October 5, with Seattle Sounders FC defeating the Columbus Crew 2–1 at Qwest Field in Seattle, WA, in front of a U.S. Open Cup record crowd of 31,311. The Sounders became the first MLS team (and first team in 27 years) to win back-to-back Open Cups.
