Coming off an emotional win in Mexico this week, FC Dallas now has a chance to improve its impressive home record.

Dallas looks to extend a 372-minute shutout streak on its own pitch when it faces the Seattle Sounders on Saturday night.

Dallas (12-6-7) is in second place in the Western Conference, five points behind MLS-leading Los Angeles and one ahead of third-place Seattle (11-5-9).

Both clubs are coming off impressive victories in CONCACAF group play this week. Dallas became the first MLS team ever to win in Mexico, defeating Pumas UNAM 1-0 on Wednesday.

The victory ended the league's 24-game winless streak on Mexican soil.

"The most important thing tonight was the attitude of the group," Marvin Chavez, who scored the lone goal, told MLSSoccer.com. "We hope to continue working in the same manner."

Dallas will try to do so in league play, in which it has two wins in its last seven games.

In its most recent MLS contest last Saturday, the club settled for a 2-all tie with Philadelphia. Both Union goals came on penalty kicks, including the tying score in the 84th minute.

Dallas plays three of its next five at home, where it is 8-2-3 and has a four-game unbeaten streak, during which it hasn't given up a goal. The club's run of 372 shutout minutes at home began in a 4-1 loss to Sporting KC on June 12.

Dallas has outscored opponents 18-8 at Pizza Hut Park, but its defense could suffer due to the suspension of George John, who was ejected last Saturday due to a yellow card violation. The defender is second on the team in minutes played and has two goals and one assist.

Seattle is unbeaten in four matches in August, two of them league games. After a scoreless draw with Chivas USA last Saturday, the Sounders defeated Comunicaciones of Guatemala 4-1 in CONCACAF action Tuesday.

"I thought we did a good job attacking," coach Sigi Schmid said. " ... I was pleased with our ability to finish our chances today."

Schmid's surging club is showing signs of improvement defensively, giving up one goal in its two league games this month after allowing eight in the final three games of July. The Sounders are 7-1-4 in their last 12 overall and 4-2-1 on the road.

Dallas won 1-0 at Seattle on May 25 on a Brek Shea goal in the 18th minute and four saves by Kevin Hartman.

Hartman can become the league's all-time leader in career games Saturday, passing Steve Ralston.

Dallas acquired midfielder/defender Jeremy Hall from Portland on Friday in exchange for midfielder Eric Alexander. Hall started 17 matches for the Timbers this season, recording three assists.
