Minnesota United changed its formation and its starting 11 considerably for Wednesday night's 3-0 loss at Real Salt Lake played at altitude and in nearly 100-degree temperatures in Sandy, Utah.
It was only the Loons' second loss in their past 12 games, a still-successful 8-2-2 stretch dating to late June in which they have been MLS' most productive team.
Still third in the Western Conference, the Loons hadn't been shut out since a 1-0 home loss to New York City FC on May 28.
They left star playmaker Emanuel Reynoso home to rest him before Saturday's game against fourth-place FC Dallas begins a stretch of the regular season's final six games.
Coach Adrian Heath made five other starting 11 adjustments and opened the game with a 4-3-3 alignment rather than his preferred 4-2-3-1. He said he did so with Saturday's upcoming game in mind and knowing his team wouldn't arrive back home until 3 a.m. Thursday.
Included were the first MLS starts for newcomers Mender Garcia and Jonathan Gonzalez. There also were halftime adjustments while trailing 2-0 that brought on substitute Robin Lod and veteran goalkeeper Tyler Miller for hurting starter Dayne St. Clair.
St. Clair dislocated a finger in that first half, Heath said, adding, "They put it back in, but it was a bit sore so we decided to not take any chances."
Real Salt Lake scored in the sixth and 23rd minutes, then nurtured that 2-0 lead until Anderson Julio scored a 79th-minute goal into an open net when Miller was caught far from goal.
