The Houston Dynamo jumped on the Montreal Impact early and never let up to claim a 3-1 win on a hot, muggy Wednesday night in south Texas.
Andrew Wenger headed in a Mauro Manotas cross from the top of the six just 52 seconds into the game, and Alex doubled the lead after a long spell of possession twenty minutes later. Homegrown and former Dynamo Academy forward Memo Rodriguez made it 3-0 with his first league goal - a driven shot from outside the box - six minutes after entering the match.
Montreal's Michael Salazar ended the shutout late with a first-time finish at the back post on a cross from Laurent Ciman.
