Chicago defeat Union, Salt Lake dry up
Casey Townsend hit the second-half winner as Chivas USA ended Real Salt Lake's strong start to the season. After a pair of victories, Real Salt Lake were expected to be too strong for a side who slid to 1-0 defeats in each of their opening two games.
But Townsend prodded the only goal of the game after 72 minutes to earn the visitors their maiden win at Rio Tinto Stadium.
It was all square in Vancouver where DC United picked up their first point of the season in a goalless draw with the Whitecaps.
