The Americans finished second in Group A after struggling to contain the Ukrainian midfielder.
A hat trick from Viktor Kovalenko led Ukraine to a 3-0 victory and sent the United States to second-place finish in Group A in the FIFA U-20 World Cup in New Zealand.
Ukraine was the better side in a physical first half, but neither team was able to find the breakthrough before the hat-trick hero got on the board in the second half.
In the 56th minute, Kovalenko took advantage of a free kick conceded by Cameron Carter-Vickers, hitting a free kick over the wall and dipping it past Zack Steffan.
