CHIVAS USA TONIGHT

at D.C. United, 4:30 PDT, FSC, FSE

Site -- RFK Stadium, Washington.

Radio -- 690 (delayed, 8 p.m.).

Records -- Chivas USA 10-10-6, United 10-13-3.

Record vs. United -- 1-0-0.

Update -- One Chivas win and one Galaxy loss will guarantee that Chivas finishes ahead of its Carson neighbor this season. Of more importance to Chivas Coach Preki, however, is maintaining the team’s current momentum (it is 4-1-1 in its last six games) and securing a playoff place for the third year in a row. Says Preki, whose team trails first-place Houston by four points: “We’re not playing to be second.”
