Dom Dwyer scored twice as Sporting Kansas City cruised to a 3-0 win over the Seattle Sounders on Sunday.
Sporting KC jumped up to fourth place in the Western Conference as Seattle rarely threatened to score in the 95-degree heat.
Dwyer opened the scoring in the 21st minute by heading home a Roger Espinoza cross from close range.
Sporting lost midfielder Graham Zusi to an apparent injury five minutes before halftime as a number of players struggled in the muggy weather.
But the hosts recovered to add to their lead before halftime as Saad Abdul-Salaam cut back to find Jacob Peterson, who delivered a well-placed finish.
