Under Mastroeni's first year as head coach, Colorado finished eighth in the West and seventeenth overall having 8 wins, 18 losses, and 8 ties having the Rapids fail to qualify for the MLS Cup Playoffs, after previously qualifying last year. Despite an upper-mid table performance to start the season, the club was plagued heavily by injuries, causing the team to go winless in their final fourteen matches of the season. In the U.S. Open Cup, the Rapids were eliminated from the tournament to the Atlanta Silverbacks. Additionally, they were unable to defend their Rocky Mountain Cup title, losing to rivals, Real Salt Lake.
