U.S. coach Bruce Arena has added Miami Fusion defender Pablo Mastroeni to the training camp roster for World Cup qualifying games against Honduras (Sept. 1) and Costa Rica (Sept. 5). Mastroeni becomes the fifth player from the Fusion roster to be named to the roster — now at 25 players. He joins club teammates goalkeeper Nick Rimando, defender Carlos Llamosa, and midfielders Chris Henderson and Preki. Mastroeni has one U.S. cap, which he earned in a 0-0 friendly with Ecuador June 7.
