The Portland Timbers stole a point late from Seattle Sounders FC, tying 1-1 on Saturday. It was a fair result given the play, which Sounders FC saw the better of early, and Portland did the same later on.
It is also full of success for the Seattle Sounders. How much success depends on how you count the numbers. For the front office of Seattle they include even contests that do not include a league that existed between the NASL and the A-League and provide the following records of the contest;

This rivalry between Portland and Seattle stretches to many things - Sounders/Timbers, Sonics/Blazers, Ducks/Huskies (Cougs/Beavs a bit too) beer, music, mass transit, whatever. But in American soccer it is the predominant rivalry, not just a rivalry.
