Carter-Vickers, a starter two years at the Under-20 World Cup in New Zealand, made a huge difference for the USA, whose defensive failings cost it on all three goals
against Ecuador, as he steadied the backline and cut out just about everything Senegal threw at the USA.
Under-20 World Cup: Scoreboard
In the first half, the USA got great work from its two central midfielders in front of Jones: Tyler Adams, who was outstanding in Concacaf qualifying and stepped in for departed Dax McCarty as a starter on the New York Red Bulls, and Eryk Williamson, who sat out his spring semester at the University of Maryland to play with the U-20s.
Adams was the best player on the field in the first half, setting up Williamson for a chance, creating one of himself and having the key touch on the Sargent goal, all in the space of five minutes.
Adams took a pass from right back Aaron Herrera and played it ahead to free De la Torre, who found Sargent coming to the ball. Sargent, who only weeks earlier was playing for the U.S. U-17s in their qualifying campaign, turned and fired a shot from 15 years past Senegalese keeper Mouhamed M'Baye.
The goal completed a hat trick of goals by Sargent: his first with his right foot, the second on a header and the third with his left foot.
In the second half, Senegal pressed for the equalizer but was undone by poor finishing. Sub Habib Gueye had an open header in the 84th minute that he could not put on target. For the game, Senegal only managed to put two of its 15 shots on target.
The USA, which faces Saudi Arabia in its final Group F game on Sunday, can finish no worse than third in its group and will have to collapse not to finish among the top four third-place teams that will join the group winners and runners-up in the round of 16.
ELSEWHERE. Five teams have six points after two games and are through to the next round: South Korea, Venezuela, Zambia, South American champion Uruguay and European champion France.
Among the winless teams are Argentina, Portugal and Germany, which have won nine U-20 championships between them.
