Kansas City have beaten Philadelphia Union 2-1, thanks to a late strike from CJ Sapong.
The hosts dominated early on but failed to turn pressure into goals until the closing stages of the first half.
Kei Kamara's trickery caused problems for the Philadelphia defence and he picked out Jacob Peterson, who drilled the ball past Zac MacMath from 12 yards to put Kansas ahead.
Graham Zusi's effort could have extended the home side's lead moments after the break but MacMath did well to block the striker's shot.
Philadelphia had the opportunity to level the scores when Danny Cruz was fouled by Matt Besler inside the box.
Michael Farfan stepped up from 12 yards and although Jimmy Nielsen was able to save the penalty, he could do nothing to keep out Antoine Hoppenot's rebound from close range.
However, Kansas recovered well to earn victory with eight minutes remaining when Sapong finished powerfully following more good work on the wing from Kamara.
