Mauro Rosales broke a tie in the 68th minute and MLS-leading FC Dallas beat Sporting Kansas City 2-1 on Sunday night.
Rosales entered as a substitute in the 63rd minute and made his first touch of the game five minutes later on a free kick that hooked over the wall into the left corner. It was first goal since joining FC Dallas (5-1-2) during the offseason.
Sporting KC (4-3-0) remained fourth in the overall standings, tied with the Eastern Conference-leading Montreal Impact.
FC Dallas tied it in the 35th minute when Michael Barrios pounced on Kellyn Acosta's long ball and powered home a right-footed shot despite a deflection off goalkeeper Tim Melia's hands. It was Barrios' fourth goal in five games.
Sporting's Lawrence Olum opened the scoring in the 22nd minute with a point-blank header to finish Benny Feilhaber's corner.
