WASHINGTON (AP) _ Freddy Adu scored on a free kick, but Chris Klein responded with a second-half goal to lift Real Salt Lake to a 1-1 tie with D.C. United Saturday night.

League-leading scorer Jeff Cunningham added his 10th assist on Klein's goal, making him the ninth player in league history to contribute 15 goals and 10 assists in a season.

Real Salt Lake (9-12-6), which entered the day two points out of the Western Conference playoffs, is 1-2-1 in its last four matches after enjoying a four-game win streak from late July to mid-August.

United (14-3-9), which had only two shots on goal despite enjoying the majority of possession, is now 1-2-4 in its last seven, but has already clinched an Eastern Conference berth.

Adu put United ahead in the final minute of the first half, bending a 23-yard free kick over the defensive wall and into the top left corner.

Klein tied it in the 65th minute, collecting Cunningham's low pass from the right side of the penalty area and driving it off the inside of the left post.

United had the best chance to win in the final minutes, with Salt Lake goalkeeper Scott Garlick making a diving save on Clyde Simm's long-range effort.

D.C. was without two of its three leading scorers. Christian Gomez (10 goals) and Alecko Eskandarian (seven goals) were both serving one-game suspensions for yellow-card accumulation.
