SAINT-DENIS, France — Tyson Gay beat Justin Gatlin in the 100 meters at the Diamond League Areva meet Friday, 12 days after losing to the 2004 Olympic champion in the U.S. trials.
Gay dipped across the line in 9.99 seconds, 0.04 ahead of Gatlin. European champion Christophe Lemaitre of France was third in 10.08.
Gay, a Lexington native, won three gold medals in the 2007 world championships, but since has been affected by various injuries and overtaken by Usain Bolt.
In other events, Javier Culson of Puerto Rico won the men's 400 hurdles, Kenya's David Rudisha took the 800 and Dejen Gebremeskel of Ethiopia won the 5,000 — all with world-leading times this year.
Never miss a local story.
Culson finished in 47.78 seconds, and Rudisha won in 1:41.54. Gebremeskel pulled ahead of countryman Hagos Gebrehiwet in the last stretch to win in 12:46.81.
Kenenisa Bekele of Ethiopia, meanwhile, won't defend his 5,000 title at the Olympics after finishing ninth.
"I'm not that disappointed because I'll run in the 10,000," Bekele said. "I wish good luck to the three Ethiopians who will be in London."
Mariem Alaoui Selsouli of Morocco also set the world's fastest time this year to win the women's 1,500 in 3:56.15 seconds. Austria's Sally Pearson did, too, winning the 100 hurdles in 12.40.
Paul Kipsiele Koech led a 1-2-3 Kenyan sweep in the men's 3,000 steeplechase.
