[UNDER-20 WORLD CUP] The USA resumes play at the Under-20 World Cup in Egypt on Tuesday when its faces Cameroon (TV: ESPN2, Galavision, live, 12:40 pm ET). Following a dismal performance in their opening game against Germany, the Americans will look turn things around in a tournament that is of particular importance to the five players who have left school or signed with a management firm hoping to parlay strong showings into pro contracts ...

SHEANON WILLIAMS. The Boston product is expected back in the starting lineup at right back after missing the opening game with an ankle injury. Williams left the University of North Carolina after one season and had a tryout over the summer at German champion Wolfsburg's second team. He spent part of the summer playing in the PDL

TONY TAYLOR. The University of Jacksonville product came out of nowhere to make the U-20s and impressed with his speed up top in the opener against Germany. He didn't play for the Dolphins as a freshman and made only six starts as a sophomore. He was recently signed by Brazilian management firm Traffic, which owns Miami FC and has gone on a spending spree, snapping up the rights to young American talent since Fernando Clavijo came on board as its U.S. soccer director. Taylor trained at Norwegian club IK Start in August.

GALE AGBOSSOUMONDE. At 17, the Togolese-born is the youngest player on the U.S. U-20s. He started at center back in the opening game. He was 2 when his family fled war-torn Togo for a refugee camp in Benin, where he spent seven years before moving to Syracuse, N.Y., with his mother, five brothers and one sister. He entered U.S. Soccer's U-17 residency program in 2007 but was too young to play on the 2007 U-17 World Cup team. Like Taylor, he signed with Traffic this year and spent part of the summer playing with Miami FC.

DILLY DUKA. The midfielder grew up in Montville Township, N.J., and spent two seasons at Rutgers, impressing with his work in midfield. He came on late in the opening game against Germany. Duka had a tryout with Belgian club Lierse and spent time training with the New York Red Bulls, with whom he had played in their youth academy.

SEAN JOHNSON. The 6-foot-4 goalie started at the University of Central Florida in 2007 and 2008. He born and raised in Georgia, where he played for the Atlanta Fire United, was called up to represent his father's native Jamaica in the 2007 U-17 Concacaf qualifiers but couldn't get a Jamaican passport in time. He has since attended a Reggae Boyz national team camp.
