Bob Kellett has a rundown of the US Open Cup history between the rivals on his Oregonlive Timbers Blog (required Timbers fan reading).
If you’re not traveling to Seattle, er Tukwila, you can listen to the game on PortlandTimbers.com (7pm kickoff).
If the Timbers win they face Chivas USA, current team of the despised Preston Burpo!
Damn sounders! I hope Chivas kick their dead fish-smelling butts!
