Arena, who guided the U.S. to a surprising quarterfinal run in the 2002 World Cup in Korea and Japan, will make the announcement at 6 p.m. EDT on ESPN's "SportsCenter."

There are several players who are locks for the team, led by goalkeeper Kasey Keller, who plays in the German Bundesliga for Borussia Monchengladbach. Keller did not play in the 2002 World Cup because of the stellar play of Brad Friedel, who subsequently retired from international competition.

Coach Arena said names will be read on Tuesday.[AP]

Keller's backups likely will be Tim Howard of Manchester United and Marcus Hahnemann of Reading.

Defenders expected to be picked are Greg Berhalter (Energie Cottbus, Germany), Carlos Bocanegra (Fulham, England), Steve Cherundolo (Hannover 96, Germany), Frankie Hejduk (Columbus Crew), Eddie Lewis (Leeds United, England), Oguchi Onyewu (Standard de Liege, Belgium) and Eddie Pope (Real Salt Lake). Cory Gibbs (ADO den Haag, Netherlands) also is in the mix.

Midfielders likely to be picked are DaMarcus Beasley (PSV Eindhoven, Netherlands), Bobby Convey (Reading), Clint Dempsey (New England Revolution), Landon Donovan (Los Angeles Galaxy), Pablo Mastroeni (Colorado Rapids), John O'Brien (ADO den Haag), Ben Olsen(D.C.United)and Claudio Reyna (Manchester City, England).

Arena may elect to have Donovan play up front with some combination of forwards Eddie Johnson (Kansas City Wizards), Brian McBride (Fulham), Taylor Twellman (New England) and Josh Wolff (Kansas City). Twellman's Revolution teammate Pat Noonan also may be selected.

D.C. United midfielder Freddy Adu, who does not turn 17 until June 2, almost certainly will be left off the squad.

Ranked fourth in the world, the U.S. is in arguably the toughest four-team group in the World Cup, Group E. The Americans first face the second-ranked Czech Republic on June 12, then traditional power Italy five days later and the dangerous Ghana on June 22. Only the top two teams from each of the eight groups advance to the knockout rounds.
