Brad Davis, Kei Kamara and Stuart Holden scored in a five-minute span in the first half to lead the surging Houston Dynamo to a 3-0 victory over visiting Toronto FC on Saturday night.
Houston (5-2-3) improved to 5-0-2 in its last seven games, while Toronto (4-4-4) lost for the second time in three matches.
Davis gave Houston a 1-0 lead in the 20th minute, sending a direct kick from just outside the upper right box under the Toronto wall and into the centre of the net, freezing goalkeeper Stefan Frei.
Two minutes later, Kamara made it 2-0 after receiving a pass from Brian Ching in the centre box and sending it just inside the left post.
Stuart Holden extended the lead two minutes later.
Saturday's game marked the return of Dwayne De Rosario to Houston. The Toronto native played three seasons with the Dynamo before being traded to Toronto FC in the off-season.
De Rosario said he didn't have much time to be nostalgic during the loss.
"When the game is going on, you're playing. You're just trying to get three points, trying to get your team into the game," said De Rosario.
"After the game, you have a little moment reflecting a little bit on the good memories that I had there, watching them play in the second half sitting back was a pleasure to watch when a team plays like that. We got beat by a very good team."
