Brek Shea scored in the 18th minute, and Kevin Hartman made four saves for his fifth straight shutout as FC Dallas beat the Seattle Sounders 1-0 on Wednesday night.
Dallas (6-3-3) extended its unbeaten streak to 5-0-2. The Sounders (4-4-5) had a four-game unbeaten streak snapped.
Andrew Jacobson started the play that led to FC Dallas' goal with a quick, short pass ahead to Shea just over the midfield line. Shea sped downfield toward the penalty area, and with Sounders goalkeeper Kasey Keller coming off his line, he fired from the top of the box into the back right corner for his fourth goal of the season.
Hartman and Dallas now have kept opponents off the board for 489 consecutive minutes. That is the longest shutout streak in MLS this season, surpassing the 414 minutes Columbus recorded from March 19 to April 23.
Hartman, who turned 37 on Wednesday and now has six shutouts for the season, has not allowed a goal since the 51st minute of a 2-1 victory at home against Los Angeles on May 1. He made two point-blank saves on shots by Seattle's Michael Fucito just two minutes apart midway through the second half to keep Seattle off the board.
