Juergen Klinsmann had to act fast in order to assemble his first roster as U.S. national soccer team coach. Three days after his formal introduction as Bob Bradley’s replacement, Klinsmann named 22 players, including D.C. United’s Bill Hamid, 20, and the rejuvenated Freddy Adu, for next Wednesday’s friendly against Mexico at Lincoln Financial Field in Philadelphia (9 p.m. ET, ESPN2, Univision, ESPN3.com). The match falls on an official FIFA date, meaning clubs are obligated to release players. The U.S. team will gather in Philly on Sunday.

Klinsmann’s first roster:

Goalkeepers: Tim Howard (Everton), Bill Hamid (D.C. United).

Defenders: Carlos Bocanegra (Saint-Etienne), Edgar Castillo (Club America), Timmy Chandler (Nürnberg), Steve Cherundolo (Hanover), Clarence Goodson (Brondby), Michael Orozco Fiscal (San Luis), Heath Pearce (Chivas USA), Tim Ream (New York Red Bulls).

Midfielders: Kyle Beckerman (Real Salt Lake), Michael Bradley (Moenchengladbach), Ricardo Clark (Eintracht Frankfurt), Maurice Edu (Rangers), Jermaine Jones (Schalke), Brek Shea (FC Dallas), José Torres (Pachuca).

Forwards: Freddy Adu (Benfica), Juan Agudelo (New York Red Bulls), DaMarcus Beasley (Puebla), Edson Buddle (Ingolstadt), Landon Donovan (Los Angeles Galaxy).

Mexico is expected to unveil its player selections today.
