The Seattle Sounders and Portland Timbers have been arch-rivals for decades, but their rivalry as MLS opponents is set to be born tonight as the Timbers travel to Qwest Field for the first of many dramatic encounters (11pm, ESPN2).
The Timbers have been riding high in recent weeks after a poor start to the season, but much of that success has come at home. Seattle will look to make full use of its own home-field advantage at Qwest Field.
