INDIANAPOLIS - Nine reigning World champions and 20 individual Olympic medalists from London will lead Team USA at the IAAF World Championships in Moscow, Russia from August 10-18.

This year’s roster features a mix of veteran athletes with a large class of newcomers to the senior world stage. Three athletes on the Team USA roster have yet to celebrate their 20th birthdays: 17-year-old Mary Cain (1500m), 19-year-old Arman Hall (400m), 19-year-old Ajeé Wilson (800m).

Athletes seeking to defend their 2011 World titles include: Jason Richardson (110m hurdles), Christian Taylor (triple jump), Jesse Williams (high jump), Dwight Phillips (long jump), Trey Hardee (decathlon), Carmelita Jeter (100m), Jenny Simpson (1500m), Lashinda Demus (400m hurdles) and Brittney Reese (long jump).

Along with the reigning World champions, four athletes enjoyed automatic bids to this year’s roster after winning their respective event in the 2012 Diamond League. These athletes include: Charonda Williams (200m), Dawn Harper (100m hurdles), Chaunte Lowe (high jump), Reese Hoffa (shot put).

While more than 20 athletes own American records indoors or outdoors, the team also boasts five athletes with world records to their names: Ashton Eaton (decathlon and heptathlon), Aries Merritt (110m hurdles), Jenn Suhr (indoor pole vault), Allyson Felix and Carmelita Jeter (4x100m relay)
