Seattle became the first Major League Soccer franchise to capture the nation's oldest soccer trophy three years in a row. It was also a record crowd for the Open Cup final.
Fredy Montero and Osvaldo Alonso scored second half goals to give Sounders FC a 2-0 victory over the Chicago Fire.
Goalkeeper Kasey Keller, who is playing his final professional soccer season, was the first to hoist the silverware in the post-game celebration.
As a product of Washington State soccer, Keller spoke about the special meaning to win the cup again on home soil.
"Winning cup finals is always something special, but to do it two years in a row at home is ridiculous!" Keller said during the radio post-game interview.
"It's just a great accomplishment for this club. In three years of existence, three cup wins in a row. It's a big credit to the squad. The fans continue to support us through everything, regardless of the competition."
Sounders FC have bigger goals this fall; winning their first MLS crown.
Seattle coach Sigi Schmid can sense his team has the special ingredients to make that happen, as he shared with Arlo White.
"This team has showed a lot of character, a lot of resiliency," said the coach. "As long as we get some good bounces along the way, you always need a little luck to win a title. We want to make more noise this year in the playoffs than we have in the past."
Seattle returns to Major League Soccer competition Saturday night at home when they host the Philadelphia Union. You can hear that match at 7 p.m. on the radio home of Sounders FC, 97.3 KIRO FM.
