The U-20s will be led by two players who played in the 2006 U-20 Women's World Cup in Russia -- Stanford's Kelley O'Hara and North Carolina's Casey Nogueira.
Eighteen of the 20 players selected by DiCicco were born in 1988 or 1989, but he did select two high school-aged players born in 1990 in midfielder Christine Nairn and forward Sydney Leroux, who previously played for Canada.
DiCicco named the roster after a week of training in Park City, Utah, in an attempt to acclimate the U.S. team to the altitude of almost 7,000 feet it will experience at Estadio Cuauhtemoc in Puebla, Mexico, where Concacaf qualifying will take place June 18-28.
"We have a very talented group with us that has excellent team depth, which is important for an event with five potential games in 12 days," said DiCicco. "There might not be a superstar yet at this stage, but we have great team chemistry. I have been really impressed with the leadership we have seen from the players, and the sense of mission they have demonstrated."
The winners of the semifinals and the third-place match at the Concacaf tournament will earn spots in the FIFA women's youth world championship being staged from Nov. 19-Dec. 7 in four Chilean cities: Coquimbo, Santiago, Chillan and Temuco.
