It marked the ColombianÆs fifth hat trick and ninth multi-goal game since joining MLS in 1998. In 87 games, Serna has scored 43 goals and notched 26 assists. GOATS: D.C. United dominated play against Chicago, which went down to 10 men early in the second half, but still managed to lose, 2-1, at home on Saturday. It marked UnitedÆs fourth straight loss. Columbus’ Duncan Oughton’s terrible back pass let in Marvin Quijano to score for the Galaxy against the Crew in a 1-1 tie.
