Alex Caskey registered his first career assist and Michael Gspurning picked up his second consecutive shutout in front a sellout crowd of 38,360.
Seattle (3-1-1, 10 points) extended its unbeaten streak to two games and earned its third shutout of the 2012 MLS season.
Colorado (3-3-0, 9 points) was handed its second straight loss and have now gone three games without a goal.
In the 63rd minute, Caskey served a corner kick that found Scott at the near post. The 31-year old right back rose up and deflected the ball inside the far post, out of reach of Rapids keeper Matt Pickens.
It was Scott’s first career goal across all competitions for Sounders FC.
Caskey recorded his first assist in his first career start. The 23-year old midfielder previously played 16 minutes as a sub against San Jose on March 31.
Sounders FC has now earned a shutout in back-to-back games and has three clean sheets in five MLS games. The last time the club earned consecutive shutouts was August 2011 (August 13 versus Chivas USA and August 20 at FC Dallas).
Sounders FC goalkeeper Michael Gspurning made just one save, but now has three shutouts in his first five MLS matches, allowing just one open-play goal so far this season.
Seattle out-shot Colorado, 18-4, including 12-1 in the second half. Seattle had 13 open-play crosses to Colorado’s six, as well as a 9-2 advantage on corner kicks.
In the fifth minute, Osvaldo Alonso intercepted a pass from Pickens in the offensive third, then passed to a cutting Fredy Montero on the left side of the box. The Colombian striker created some space and got off a strong shot that was saved nicely by Pickens.
Caskey and Scott nearly combined for a goal in the 13th minute when Caskey’s free kick found Scott in the box, but his header missed wide.
Montero was dangerous throughout the match. In the 29th minute, Alonso rolled a free kick to Montero for a shot from 35-yards out, but the attempt sailed high. In the 37th minute, Eddie Johnson led Montero up the middle, but Pickens charged out from the box to make a sliding clearance.
In the 50th minute, a Montero free kick from 30-yards out bent around the Colorado wall but missed just wide of the goal. After a run in the 89th minute, Montero chipped a shot from 20-yards but Pickens punched it over the bar.
Johnson made his first start for Sounders FC. He played 24 minutes as a sub in Seattle’s last match at D.C. United. His last regular season start was October 20, 2007 for Kansas City against FC Dallas.
Sounders FC returns to action in two weeks on April 28 when the Rave Green travel to Chicago to take on the Fire at 5:30 p.m. PT.
