American runner Sanya Richards has set a world's best time and won the women's 400-meters race at the Weltklasse Golden League meet in Zurich, Switzerland.
Richards won in 49.3 seconds with world bronze medalist Novlene Williams of Jamaica second (50.85). Senegal's Amy Mbacke Thiam was third (50.95).
Richards remains in the running for $1 million Golden League jackpot, which is split among athletes who win their event in all six Golden League meets. The only other athlete with a shot at the jackpot is Russian pole vaulter and world champion Yelena Isinbayeva.
Only two Golden League meets remain on the schedule, in Brussels September 14 and Berlin September 16. If no athlete wins all six meets, those with five victories are awarded their share of half the original prize $500,000.
In other events, Portugal's Francis Obikwelu won the men's 100-meters in 10.17 seconds. Jaysuma Saidy Ndure of Norway second (10.20 seconds). Marlon Devonish of Britain was third (10.20). Triple world champion Tyson Gay of the United States did not run because of fatigue.
Elsewhere, two-time European champion Mehdi Baala of France won the men's 1,500 meters race in three minutes, 38.62 seconds.
Christine Arron of France won the women's 100-meters in 11.17 seconds. American Torri Edwards was second (11.22) and compatriot Camelita Jeter was third (11.24).
American runner Xavier Carter - who failed to qualify for the recent world championships in Japan because of a leg injury - won the men's 200-meters race in 19.92 seconds. World silver medalist Usain Bolt of Jamaica was second (20.19) with Johan Wissman of Sweden third (20.47).
