KANSAS CITY, Kan. - Kei Kamara and Graham Zusi exploited the Union defense with first-half goals, and the Kansas City Wizards broke an eight-match winless streak with a 2-0 victory on Thursday night.
Kansas City (3-5-3) won for the first time since beating Colorado, 1-0, at home on April 10.
The Union, who played a man down from late in the first half on, dropped to 2-7-1 heading into the World Cup break of their expansion season.
They next play the Seattle Sounders on June 27 in the sold-out opener of PPL Park in Chester.
In this game, Kamara scored in the ninth minute and Zusi picked up his first Major League Soccer goal in the 35th, each time after staying onside and beating the left side of the Union's back line.
Kamara took a feed from Davy Arnaud and put a rocket into the upper-left corner, and Zusi went to the lower-left corner after Ryan Smith found him in space just inside the penalty area.
Union defender Michael Orozco was sent off in the 42d minute, after drawing his second yellow card for a reckless tackle on Kansas City's Josh Wolff.
Wizards keeper Jimmy Nielsen made two saves and earned his fifth shutout of the season.
