Amalia Villarreal, who's been playing club ball for her home state Michigan Jaguars and Texas' Solar SC, scored and assisted in the win over Jamaica. The 16-year-old's goal within three minutes of kickoff was her team-leading eighth of the tournament (in five games).
Villarreal assisted on captain Riley Jackson's 41st minute goal after Charlotte Kohler's 2-0 strike. The USA, which outshot Jamaica 38-2, got its final goal from Melina Rebimbas, assisted by Onyeka Gamero, in the 56th minute.
The assist by Gamero of California's Beach FC was her team-leading sixth of the tournament. Also, her deflected cross set up Kohler's goal.
