Expansion franchise St Louis City's perfect start to their inaugural MLS season was ended by Minnesota United who triumphed 1-0 after Luis Amarilla's 78th-minute penalty on Saturday.
City had made MLS history by winning their first five games but that was ended by the Loons with Amarilla drilling home the spot kick after a needless challenge by Kyle Hiebert.
Hiebert brought down Amarilla just inside the box with a rash tackle when Jakob Nerwinski appeared to have Kervin Arriaga's wayward pass under control.
Substitute Samuel Adeniran came closest to equalising for St Louis, with a 95th-minute shot going over the bar after a great first touch from Klauss' right-wing cut back.
St Louis remain top of the table with 15 points from six games, but unbeaten Minnesota climb up to fourth in the Western Conference.
