Chivas USA's difficulties holding leads reared up again Saturday, when the Philadelphia Union overcame a halftime deficit to pull out a 3-2 victory. Danny Mwanga's team-best fifth goal of the season, a superb shot off a quick turn, settled things in the 82nd minute.
Michael Umaña gave the Goats a 28th-minute lead -- finishing following three headers after Union goalkeeper Fayed Mondragon punched away a corner kick -- and Justin Braun pulled them even in the 77th after Veljko Panunovic and Carlos Ruiz netted second-half goals.
Chivas (4-7-5) has surrendered six leads in its last six games and has won just once in its last seven. Philadelphia (7-4-5) is atop the Eastern Conference, three points ahead of New York, which plays Sunday at Chicago.
