Commerce City, CO -- (Sports Network) - The Chicago Fire moved into a tie with D.C. United at the top of Major League Soccer's Eastern Conference table with a 2-1 win at the Colorado Rapids on Saturday night.

First-half goals by Marco Pappa and Wilman Conde less than eight minutes apart gave the visitors a commanding lead and they withstood a late charge to hang on.

Pappa gave Chicago a 1-0 lead at the half hour mark, converting a Baggio Husidic feed for his fifth goal of the year.

Conde added his second goal of the season in the 37th minute when he headed home a Cuauhtemoc Blanco corner kick to make it 2-0.

Jacob Peterson pulled an unassisted goal back for Colorado in the 76th minute, but that was as close as the home side could get.

The Rapids (5-4-6) will aim to rebound when they host FC Dallas next Saturday, while Chicago (6-3-6) hosts Columbus the same day in its next MLS fixture.
