In a match that featured intense physical play, defensive dominance, atrocious refereeing and a near-brawl, the Seattle Sounders drew 0-0 with the Houston Dynamo on Thursday night at Qwest Field. Seattle defender Patrick Ianni, a last-minute replacement in the starting lineup, came closest to scoring by hitting the crossbar, but the home side also needed a few clutch saves by Kasey Keller to salvage the draw.
