Will Bruin scored the only goal of the game as Houston Dynamo recorded a 1-0 victory over Columbus Crew at the BBVA Compass Stadium.
It was Columbus who made the brightest start to the match, with Bernardo Anor seeing an early shot saved by Tally Hall following good work from Waylon Francis.
Jairo Arrieta should have put the visitors ahead midway through the first half after collecting a pass from Dominic Oduro, but he failed to beat Hall with a powerful effort.
Houston found their form towards the end of the first half, with Giles Barnes having a greater impact on the contest, but the opening goal would not arrive until the 50th minute.
After winning a free kick in a dangerous position, Houston benefited from an inviting Brad Davis delivery as Bruin beat his marker to head past a helpless Steve Clark.
Hall ensured that Houston remained in control of the game in a crucial few minutes in the middle of the second half as he made saves to deny both Francis and Arrieta.
Despite missing the opportunity to double their lead when David Horst headed just wide of the top corner, Houston remained calm in the closing stages to hold on for the win.
