NEW YORK  -- Defenders John Brooks, Timmy Chandler and DeAndre Yedlin are among the 30 players selected by U.S. coach Jurgen Klinsmann on his 30-man preliminary roster.

Midfielder Julian Green, who made his national team debut last month, and forwards Terrence Boyd and Chris Wondolowski also are among the players picked who will try to earn spots at the Americans' pre-World Cup training camp, which opens Wednesday at Stanford, California.

Klinsmann must submit a 23-man roster to FIFA by June 2.

Among those left off Monday were defender Tim Ream; midfielders Sacha Kljestan, Brek Shea, Jose Torres and Daniel Williams; and forwards Herculez Gomez and Juan Agudelo.

Half the players are from Major League Soccer, with four each from England's Premier League and Germany's Bundesliga.
