INDIANAPOLIS (AP) – The makeup of what promises to be a powerful U.S. squad at the world track and field championships was unveiled Wednesday, with Maurice Greene included in the 400-meter relay pool.

The U.S. squad includes 27 Olympic medalists and is even younger than the youth-dominated team that won a surprising 25 medals at the Athens Games. USA Track and Field has set a target of 17 to 29 medals at the world championships, to be held Aug. 6-14 in Helsinki, Finland.

Greene, a three-time world champion and 2000 Olympic champion in the 100, pulled up with a hamstring injury in the finals at the U.S. championships and failed to make the team in an individual event.

Farmington native Kevin Eastler will be competing in the 20-kilometer racewalking competition.

The 31-year-old sprinter still is bothered by the injury. He withdrew from last Friday’s Crystal Palace meet in London. Greene’s coach, John Smith, also is coach of the U.S. men’s team.

The women’s 400 relay pool is made up of Angela Daigle and LaShaunte’a Moore.

Monique Hennagan, Suziann Reid and Moushaumi Robinson are in the women’s 1,600 pool.

Any other athlete on the U.S. team is eligible for the relays.

The average age of the U.S. team is 26.5 years, with 45 percent of them under 25.

Among the team members are Olympic gold medalists Justin Gatlin in the 100, Jeremy Wariner in the 400, Dwight Phillips in the long jump and Joanna Hayes in the 100 hurdles. Shawn Crawford is the Olympic 200 champion, but has withdrawn from that event because of a foot injury. He still plans to compete in the 100 and be available for the 400 relay.

Eight of those on the roster had world-leading marks for 2005, as of Wednesday: Wariner in the 400, Phillips in the long jump, Wallace Spearmon in the 200, Kerron Clement in the 400 hurdles, John Godina in the shot put, Allyson Felix in the 200, Sanya Richards in the 400 and Michelle Perry in the 100 hurdles.
