The penalty call on Stefan Frei. Just a poor call in my opinion:
The Sounders FC 1-0 loss to Sporting Kansas City can be summarized in two animated gifs. In a game that surely at the very least both teams deserved to share points or possibly Seattle could've snatched and grabbed all three, two plays turned this game in very short order.
