The game was fairly even in the first half, with neither Houston nor Tigres able to take control, although the hosts had a good chance early on when Boniek García played in Alberth Elis, but he couldn’t find the target.
Houston put on a good defensive performance in the first half, and Tigres’ opportunities were limited. A header from Enner Valencia in the 28th minute was saved by Joe Willis, who intercepted a cross by Luis Rodríguez for Valencia soon after that.
In the second half, the Dynamo had a chance following a defensive error, as Tommy McNamara won the ball and connected with Romell Quioto. He laid the ball off for Mauro Manotas, whose effort failed to find the target.
Then, with time winding down, Tigres struck. In the 78th minute, Enner Valencia and Julián Quiñones combined well with a give-and-go that ended with Valencia stabbing the ball home to make it 0-1.
Three minutes after that, the universitarios added a second, with Valencia playing a long ball to Quiñones, who brought it down at the top of the box and beat Willis from just outside the area to make it 0-2 and give the visitors a significant advantage in this quarterfinal series.
With the 0-2 win, Tigres will advance with a win, a draw, or a one-goal loss in next week’s second leg, while the Dynamo need to score at least three goals while winning by at least two (ex: 3-0, 3-1, 4-2) to win the series outright; a 0-2 Houston win would send the game to penalties.
