Justin Braun hit his second hat-trick of the season in a blowout win for Chivas USA. Houston had JeVaughn Watson ejected to complete its misery.
Braun got his first goal on 31 minutes when Ante Jazic, fresh off an injury and back in the side, sent in a lovely cross that the forward poked in to open the scoring.
It took less than 10 minutes for Braun to knock home his second when he latched onto a deflected pass and broke in alone, calmly finishing past Tally Hall to double Chivas USA's lead. The striker would have to wait until the 86th to round out his night, finishing another cross from Jazic and putting an end to any doubts that remained about the outcome of the match.
Chivas USA will now face a brutal five-game road swing that kicks off with a trip to FC Dallas to end July while the Dynamo will close out the month with a home match against the Seattle Sounders.
