Seattle (11-5-9, 41 points) finished with a 10-4 advantage in shots and Kasey Keller collected his 28th career shutout. Alvaro Fernandez had the game's best scoring opportunity for Sounders FC but his penalty kick in the 19th minute deflected off the left post.
Chivas USA (7-8-9, 30 points) goalkeeper Dan Kennedy pushed the penalty rebound out for a corner kick and made two saves.
Fernandez's penalty was set-up when he maneuvered in the box and his cross was batted down by the arm of Chivas defender Michael Umana.
Keller's biggest test came in the 40th minute. Alejandro Moreno flicked the ball into the path of Nick LaBrocca, charging into the box unmarked. Keller charged off his line to block the ball with his legs, deflecting it out to Zach Scott who cleared it from the zone.
Kennedy made two big stops in the second half. In the 50th minute, Erik Friberg's shot from outside the box deflected to Pat Noonan and his off-balance 8-yard attempt was rolling goalward when Kennedy dived to his left to push it wide.
With 13 minutes left, Fernandez was denied again. James Riley sent a cross to the back post and Fernandez's shot from close range was blocked at the left post by Kennedy.
Seattle is now 0-2-3 all-time in matches when a penalty kick is missed or saved.
Noonan made his first MLS start since July 15, 2010. He finished with a team-high three shots before leaving in the 69th minute.
Sounders FC have lost only once in their last 12 matches (7-1-4). It was the 44th consecutive sellout for a home MLS match.
Chivas USA held the advantage in corner kicks, 5-4, and ended the game with 12 fouls to Seattle's 18.
Five yellow cards were issued in the game, with three going to the Goats.
