U.S. Open Cup matches don't generally have the heated rivalry factor, but the Portland Timbers-Seattle Sounders third-round match-up isn't your normal rivalry.
Forged from the days of the old NASL, and kept alive for decades in the A-League and USL, Timbers-Sounders is one of the most intense, and arguably the best rivalry in the United States.
That rivalry has been put on hold since the Sounders joined Major League Soccer, but the U.S. Open Cup has brought it back to life, with the Timbers playing host to the Sounders tonight (10pm).
