The balance of power in MLS' Texas rivalry appears to have swung to FC Dallas.
Dallas is unbeaten in its last seven matches and has not allowed a goal in 489 consecutive minutes heading into Saturday night's road matchup with the Houston Dynamo.
Houston is 7-3-6 all-time against Dallas, which has posted two wins and a tie in the last three meetings. Dallas had never won in Houston before a 1-0 victory last May 5.
Dallas had been 0-5-2 in MLS regular-season games at Robertson Stadium and 0-7-2 in all competitions. These teams are playing for El Capitan, a replica 19th-century cannon given to the winner of the season series, with a return matchup set for Dallas on Sept. 24.
Both teams played Wednesday, and fatigue could be a factor. Dallas improved to 5-0-2 in its last seven with a 1-0 victory at Seattle on Brek Shea's goal in the 18th minute.
"We go into every game thinking that we are going to find a way to get three points," coach Schellas Hyndman told FC Dallas' official website. "Our guys played with extreme determination and desire to get a result, so a great win for us."
Goalkeeper Kevin Hartman and his defense helped maintain the goalless streak for opponents. The club-record run is the longest shutout streak in MLS this season, surpassing the 414 minutes Columbus recorded March 19-April 23.
Shea scored his team-high fourth goal for Dallas (6-3-3), which continues to play without injured reigning league MVP David Ferreira. Hyndman has used the same 11 players for each of the last four games, with Eric Alexander starting all of them.
"We had to work hard for a long period of time because Seattle was throwing a lot of numbers at us and some quality at us," Hartman said. "I think there's a real inner fortitude and a real belief in this team that we can get things done and get results in difficult places to play like Seattle."
Houston is 0-3-2 in its last five after a 1-0 loss at Los Angeles. The Dynamo were outshot 14-5 and outplayed for most of the match.
"I think we are a little disappointed," captain Brad Davis told the Dynamo's official website. "I think we could play better, that's for sure."
The Dynamo (3-4-5) have been shut out in two of their last three games -- both on the road. They have fared better at home with 11 goals over their last five there.
"It is just one of those that you have to take on the chin a little bit and we have a game Saturday so we are looking forward to that," midfielder Geoff Cameron said.
