Roland Lamah scored twice and Clint Dempsey was sent off as FC Dallas beat Seattle Sounders 3-0 in MLS on Sunday.
Lamah opened the scoring in the 20th minute from Michael Barrios' pass across goal.
Maximiliano Urruti made it 2-0 in the 58th minute by curling a shot around Stefan Frei and then Lamah chipped Frei five minutes later after a one-two with Anton Nedyalkov.
Seattle were reduced to 10 men in the 37th minute after officials reviewed a video showing Dempsey's elbow making contact with Jacori Hayes.
Dempsey will be suspended for the Sounders' next MLS match against Montreal Impact on Saturday, March 31.
