The Seattle Sounders of the USL-1 were made defunct in 2009 due to the introduction of the MLS expansion franchise of the same name. In 2009, it was announced that expansion teams would be allotted to Vancouver and Portland. Both teams were named after their predecessors, ensuring the continuation of the rivalry. Supporters of the Timbers and Whitecaps decided to continue the Cascadia Cup without the Sounders for two years while playing in the USL. In 2009, supporters of the Timbers and Whitecaps only included regular season USL-1 matches played between the teams and Portland won the cup for the first time. Some Sounders supporters wished to include a preseason victory over Vancouver and a US Open Cup match win at Portland for consideration in the cup standings while others believed that the Cascadia Cup competition should be suspended until 2011. Portland won the Cup for a second consecutive year in 2010.
