U.S. Under-17 coach Wilmer Cabrera has 39 players training at the IMG Academies -- all born in 1992, 1993 and 1994.
Three players will be part of the program for the first time as Cody Cropper, Jose Perez and Flores.
Cropper, a 6-foot-4 goalkeeper, is the only residency player from Minnesota. He spent time in the USL Minnesota Thunder and Reading Rage's academy programs and had a trial at Wolves in his father's native England.
Perez joins the U-17s from the FC Dallas Juniors, who are having a sensational first year in the Development Academy.
Flores, the lone professional player on the roster, hails from El Cajon, Calif.
Martinez, one of the U-17s' top prospects, was sent home last fall for unnamed disciplinary problems but returned to the program. Jack McInerney and Martinez were the team's leading scorers in 2008, both registering six international goals.
Zambian-born Charles Renken, still only 15, returns for his fifth semester in Bradenton.
Cabrera also welcomes back 14 players who are entering their fourth semester of the program.
Luis Gil and Tyler Polak led the squad with 13 starts in 2008, while Stefan Jerome and Joseph Gyau each made 16 appearances.
Cabrera's boys will play in the 2009 CONCACAF Under-17 Championship, which will be held in late April. The USA will attempt for its 13th consecutive FIFA event at this level.
