The home side were on the receiving end of a narrow defeat last time out, while their visitors showed great resolve to hold on for a hard-fought win.
Match preview
Sporting Kansas City just about came away empty-handed from a thrilling 3-2 contest against Inter Miami at the Arrowhead Stadium on Sunday.
Peter Vermes's men took the lead early on through Erik Thommy but found themselves trailing to strikes from Diego Gomez and Lionel Messi before Thommy levelled matters just shy of the hour mark, only for Luis Suarez to decide the game 19 minutes from time.
As a result, the Wizards have dropped down to ninth place in the Western Conference of the MLS table, one point ahead of the chasing pack in the race for playoff contention.
Coming up next is the challenge of an opposing side who have just about being on the wrong end of this fixture more times than not with two wins and three defeats from the previous five editions.
Having let in three goals in each of their last three home involvements, Sunday's hosts will need to keep things tight at the back if they are to secure maximum points in front of their fans.
St Louis City snapped a run of five games without a win stretching back to early March by beating Austin FC 1-0 at the CITY PARK on Sunday.
Bradley Carnell's men opened the scoring three minutes shy of the hour mark through Joao Klauss, and that was enough to get the job done in a drab affair.
With 11 points from eight matches so far, the Missouri-based outfit sit eighth in the Western Conference, outside the final automatic playoff spot only on goal difference.
Winless in six consecutive away outings leading up to this weekend's affair, Sunday's visitors have been abysmal on the road of late and will be keen to turn their fortunes around.

There is little to pick between the sides, and Sunday's clash could easily swing either way. That said, we just about fancy the home side to edge out their visitors and come out on top in the end.
