MLS: Seattle 0, D.C. United 0 (tie) WASHINGTON, April 7 (UPI) -- Marc Burch's close-in header for Seattle bounced off the post in stoppage time Saturday, letting D.C. United escape with a 0-0 draw with the Sounders. After battling through a scoreless match, Seattle had a golden opportunity late in the game when United goalie Joe Willis punched away an Osvaldo Alonso shot from outside the box, but the ball came right to Burch 6 yards from the goal. His header, however, clanged off the post and United (1-2-2) held on for a point. Seattle (2-1-1) got its best scoring chance in the 23rd minute when Albanian striker Hamdi Salihi picked up a Nick DeLeon cross but also hit the bar from 6 yards out.
