Western Conference-leading Colorado Rapids made it six MLS games without defeat with a hard-fought 1-0 victory over slumping Sporting Kansas City.
Dillon Serna was the hero on Wednesday, his 78th-minute goal lifting the Rapids past Sporting KC and to a sixth consecutive win in Colorado this season.
After Sporting KC defender Ike Opara was sent off for a second bookable offence 14 minutes from time, Colorado went up to the other end two minutes later and consigned the visitors to a seventh winless match via Serna's long-range effort.
