The Seattle Sounders are likely eager to resume MLS play.
Seattle (10-4-8) hasn't played a league game since defeating Colorado 4-3 on July 16. Fredy Montero scored his third goal in two games with a diving header in the 82nd minute and Mauro Rosales scored off a pass from Montero two minutes later for the Sounders, who have an MLS-best 15 goals in the final 15 minutes of matches.
Seattle hasn't had much trouble scoring lately in MLS play, reaching the three-goal mark three times in its last five games. The Sounders have won five of six and are 6-0-3 since losing 2-1 to FC Dallas on May 28.
Although Seattle is in the midst of the longest unbeaten streak in the club's three-year history, it is coming off a couple of forgettable performances.
The Sounders were embarrassed by Manchester United on July 20, suffering a 7-0 defeat to the English Premier League powerhouse.
Seattle's offense again stumbled Tuesday against San Francisco in the first leg of the preliminary round aggregate-goals CONCACAF series, losing 1-0.
"We have got to show our ability to come back and score some goals," coach Sigi Schmid told the Sounders' official website.
A game against Houston could help Seattle's offense get back on track.
The Dynamo (5-7-9) are coming off last Saturday's 3-0 loss to Chivas USA, the fifth time in nine MLS matches they surrendered at least two goals. Houston's offense is also struggling, having been shut out in three of its last six league games.
"We're upset because we train well and do well together, and then in games, we get out there and it all falls apart," midfielder Brad Davis told the Dynamo's official website.
Houston didn't have many scoring chances against Chivas, managing three shots on goal in falling to 2-6-6 in its last 14 matches.
"(We need to) try and forget this as soon as possible but realize the mistakes that we made," coach Dominic Kinnear said. "(We need to) understand that we have a good team in Seattle coming to our place, and we have to be ready to play them."
The Dynamo are 2-0-1 all-time against the Sounders in Houston, including a victory in the 2009 MLS playoffs.
In the first meeting of the season in Seattle on March 25, the teams played to a 1-all tie. Geoff Cameron opened the scoring for Houston in the 42nd minute and Steve Zakuani netted the equalizer in the 80th.
