SEATTLE -- Clint Dempsey scored off a corner kick in the 52nd minute and the Seattle Sounders beat the Colorado Rapids 1-0 on Saturday to extend their overall MLS lead.
Seattle goalkeeper Stefan Frei had his league-leading eighth shutout. The Sounders (15-7-3) boosted their points total to 48, assuring that they'll retain the Western Conference and Supporters Shield leads, regardless of any other results this weekend.
Marco Pappa's corner kick from the right side floated into the middle of the penalty area, Dempsey ran onto it and blasted a right-footed shot from 11 yards past goalkeeper Joe Nasco.
Colorado (8-12-6) lost its sixth straight, tying the franchise record set in 1999 and matched in 2012. The Rapids, who haven't won since beating Chivas USA 3-0 on July 25, have been shut out three times and outscored 16-6 during the losing streak.
The 30-year-old Nasco was making his MLS debut.
