About Seattle Sounders FC (from Wikipedia)
Seattle Sounders FC is an American professional soccer club based in Seattle, Washington that competes in Major League Soccer (MLS). Sounders FC was established in November 2007 as an MLS expansion team, making it the 15th team in the league. Fans chose the Sounders name through an online poll in 2008, making the Seattle Sounders FC the third Seattle soccer club to share the moniker.
The club’s majority owner is Hollywood producer Joe Roth, and its minority owners are Adrian Hanauer, Paul Allen and Drew Carey. Two-time MLS Cup winner Sigi Schmid is the club’s head coach. Sounders FC home matches are played at CenturyLink Field. Along with several organized groups, a 53-member marching band called ‘Sound Wave’ supports the club at each home match. Seattle competes with rival MLS clubs Portland and Vancouver in the Cascadia Cup.
Sounders FC played its inaugural match on March 19, 2009, winning 3–0 over the New York Red Bulls. Seattle has sold out every league match, set MLS records for average attendance, led the league in season ticket sales, and qualified for the MLS Cup playoffs in each of its first three seasons. In 2009, Sounders FC became the second expansion club in MLS history to win the U.S. Open Cup, and in 2010 became the first ever MLS club to repeat as Open Cup champions. Sounders FC won a third consecutive Open Cup in 2011, defeating the Chicago Fire 2–0.
