Dynamo advance in overtime

HOUSTON —  Brian Ching scored six minutes into overtime and the Houston Dynamo advanced to the Western Conference final for the third time in four years with a 1-0 win over Seattle on Sunday.

The teams dueled to a scoreless tie in the first leg of their two-game semifinal on Oct. 29, setting up the winner-take-all match in Houston. Fittingly, the league’s top two defensive teams during the regular season played 90 more minutes without a goal before Ching’s game-winner.

The Dynamo advances to the single-game Western final to face the Galaxy.

Houston improved to 5-1 at home in the playoffs and 9-1-6 at home this season.

The Sounders, an expansion team, wrapped up their inaugural season by losing to Houston for the first time in five games (2-1-2).
