“The Cup stays here” was the phrase blazoned before the match by Sporting Kansas City. And Yohan Croizet’s wonder strike made sure that the US Open Cup trophy would stay for at least another round. Sporting Kansas City, the defending Lamar Hunt U.S. Open Cup Champions, hosted FC Dallas, the 2016 champions who were knocked out by Kansas City in last season’s quarterfinals, Saturday evening at Children’s Mercy Park for a round of 16 matchup. In a see-saw match began on shaky ground for the hosts, two goals by Daniel Salloi and Croizet’s striker outdueled those by FC Dallas’s Carlos Gruezo and Roland Lamah.
