The Philadelphia Union traded Cristian Maidana to the Dynamo in the offseason.
On Saturday night Maidana made them pay.
Maidana's free kick in the fifth minute of second-half added time provided the difference in Houston's 1-0 victory over the visiting Eastern Conference leaders in front of 18,457 fans at BBVA Compass Stadium. Maidana was a second-half substitute.
The victory snapped a five-game MLS winless streak for the Dynamo (4-8-5) and pulled them even with Seattle in ninth place in the Western Conference standings. It is the first time the Dynamo have not been in sole possession of last place in several months.
