A late red card and stoppage-time strike from Sporting KC forward Dominic Dwyer were the difference-making plays, as the Colorado Rapids lost for the first time in the 2014 MLS season.
After giving up a quick goal to begin the second half, the Rapids converted two penalty kicks opportunities to take a 2-1 lead in the 78th minute. But less than a minute later, Kansas City midfielder Benny Feilhaber tied the game at 2-2 with a shot from inside of six- yards from goal.
In the 85th minute, defender Marvell Wynne drew his second yellow card and was sent to the locker room, forcing the Rapids to play the final minutes with only 10 players. Sporting KC would take advantage seven minutes later, with Dwyer scoring off a hard shot from inside the 18-yard box.
"There were a couple other half chances for us in the first half that if we put away, it might be a different story," said Rapids captain Drew Moor. "But even in the second half after giving up the goal, we did well to get back in the game and even to take the lead again. It was just a crazy second half."
Despite the loss, head coach Pablo Mastroeni liked the way his team performed against the defending MLS Champions.
"Obviously it's early in the season, but I think the guys put up a fight," he said. "We had similar formations, similar mindsets, both teams trying to press and win field advantage, no one giving up the field advantage very easily, and it was a cagey affair. It's a great game to build on, there's a lot of positives that came out of that game, and obviously some things that we need to correct moving forward."
