SAfrican teen wins 800 despite gender questions

BERLIN (AP)Track and fields ruling body is investigating whether a South African teenager meets the requirements to compete as a woman amid concerns about her dramatic improvement in times, muscular build and deep voice.

Caster Semenya easily won the 800-meter gold medal at the world championships Wednesday, her dominating run coming on the same day the IAAF said she was undergoing a gender test.

Semenya took the lead at the halfway mark and opened a commanding lead in the last 400 meters to win by a massive 2.45 seconds in a world-leading 1 minute, 55.45 seconds. Defending champion Janeth Jepkosgei was second and Jennifer Meadows of Britain was third in 1:57.93.

After crossing the line, Semenya dusted her shoulders with her hands. She did not speak to reporters after the race or attend a news conference.
