WASHINGTON (AP) -- Abdul Thompson Conteh scored in the 58th minute to lift D.C. United to a 1-1 tie with the Colorado Rapids on Saturday night.

Imad Baba scored for the Rapids (2-8-5), whose winless streak was extended to eight games at 0-5-3. Colorado has not won since May 12.

The United (5-8-1) are 2-6-1 in their past nine games.

Midfielder Carlos Valderrama and goalkeeper Scott Garlick, acquired by the Rapids in a six-player trade with Tampa Bay on Thursday, made their Colorado debuts.

The game, which followed a 2-0 victory by the Washington Freedom over the Carolina Courage in the first match of a WUSA-MLS doubleheader, drew 30,271. On May 12, a doubleheader featuring the Freedom and United attracted 36,528.

Colorado took a 1-0 lead in the 41st minute on Baba's first goal of the season when he took a loose ball just outside the penalty area, dribbled around a defender and sent a right-footed shot that surprised Mike Ammann, who didn't react until the ball was by him.

Conteh's team-high ninth goal tied when he collected a right-side pass from Jaime Moreno, pulled Garlick out and down and scored into an empty net from 6 yards out.
