The Dynamo had to go the distance, but it was their sprinter who made sure they won the race.
Speedy Honduran winger Alberth Elis scored in the sixth minute of extra time Thursday night to give the Dynamo a 1-0 victory over Sporting Kansas City in the knockout round of the MLS playoffs at BBVA Compass Stadium.
The No. 4 seed Dynamo advance to the Western Conference semifinals where they will face the No. 1 seed Portland Timbers in a two-leg series beginning Monday at BBVA Compass Stadium.
The second leg will be played Nov. 5 at Portland.
