Two first-half goals led Chicago to a morale-boosting win over the reigning MLS champion. Dominic Oduro and Cory Gibbs scored the goals.
Chicago did the damage with two first-half goals. Dominic Oduro took advantage of an understandably tired Rapids side, which had played in the CONCACAF Champions League midweek, to open the scoring in the 17th minute. It was his ninth goal of the year. Pavel Pardo provided the assist.
"It was a good ball from Pavel," Oduro said. "Before the game he told me, 'Look out for me. When I see you open I'll give you the ball.' It definitely made my confidence go up."
Cory Gibbs headed a Sebastian Grazzini cross emphatically home from six yards to double the lead. Pardo created the second goal as well by finding Gazzini.
Pardo's replacement, Daniel Paladini, cleared a long shot off the line, but other than that the Fire closed out the game simply to seal the win.
When Colorado players were asked after the match what they would have changed to get the result goalkeeper Matt Pickens suggested not traveling to Honduras midweek. Jeff Larentowicz wanted a better start.
"In the first half although we had a lot of the ball, we were a little sloppy," the midfielder said. "If we were a little bit more sharp with the battle, I think we could've gotten the result we wanted."
