CHICAGO – Defenders Danny Califf, Michael Orozco and Marvell Wynne were added to the U.S. roster for next month's World Cup qualifiers against Cuba, and Trinidad and Tobago.

Midfielder Ricardo Clark also was among 20 players selected Thursday by U.S. coach Bob Bradley. Injured midfielder Pablo Mastroeni was dropped along with defender Jay DeMerit.

The U.S. team gathers in Miami starting Monday and leaves Sept. 4 for Havana, where it plays Cuba two days later. The Americans host T&T at Brideview, Ill., four days later.

Eighteen players can dress for each match. Defender Steve Cherundolo is suspended for the game at Cuba following his ejection Aug. 20 at Guatemala, where the Americans won 1-0 in their semifinal round opener. Defender Oguchi Onyewu, goalkeeper Tim Howard and forward Clint Dempsey would be suspended if they receive one more yellow card.

Thirteen players are based outside the United States, and six were members of the U.S. Olympic team in Beijing. The roster includes forward Eddie Johnson, loaned last week to Cardiff by Fulham in England.
