Brad Evans blasted in a hard shot in the 28th minute and Eddie Johnson added an insurance goal during second-half stoppage time to give the Seattle Sounders a 2-0 victory over the Colorado Rapids in the MLS Western Conference knockout playoff game Wednesday night.

The No. 4 seeded Sounders (16-12-7) limped into the postseason on a seven-game winless streak, but advanced to face the No. 1 Portland Timbers in the two-leg, aggregate-goals West semifinals. The first game will be Saturday in Seattle.

The No. 5-seeded Rapids finished the season 14-12-9.
