A late free kick from Kei Kamara, his ninth goal of the season, gave Sporting KC all three points in Toronto.
The only goal of the game came with less than 10 minutes remaining. Graham Zusi shifted a free kick a few feet to the right, and Kei Kamara blasted it into a congested box. It took a deflection and slipped past Milos Kocic to secure three road points for Kansas City.
Kocic had made seven saves to keep TFC in the match.
