Reigning world and Olympic champion Justin Gatlin cruised to victory to successfully defend his men's 100-meter title at the Seiko Super meet in Yokohama on Monday.
Gatlin, who completed a golden sprint double at last month's world championships in Helsinki, powered home in 10.04 seconds to edge out Nigerian Olusoji A. Fasuba and Christopher Williams of Jamaica, who tied for second in 10.13. Japan's Shingo Suetsugu came fourth in 10.17.
"I am really pleased with the season this year and I feel I have established better credit to my name. I was more consistent this year," said Gatlin. "Hopefully next year I can run quality races with fast times on fast tracks."
In the day's biggest surprise, world and Olympic champion Yelena Isinbayeva failed in all three of her attempts starting from the 4.50-meter mark and finished without a record in the women's pole vault.
The 23-year-old from Volgograd, who nailed a world-record 5.01 meters vault for her 18th world mark in Helsinki, had been previously unbeaten in 14 indoor and outdoor competitions this year.
China's hurdling ace Liu Xiang added to his victory in Shanghai at the weekend when he breezed to victory in the men's 110-meters hurdles.
Liu, winner at last year's Athens Olympics, led from start to finish and crossed the line in 13.08 seconds.
In the women's 100 meters, American Allyson Felix, the world gold medalist in the women's 200, won in 11.05.
In the 400-meter hurdles, Jackson Bershawn, who led the United States to a 1-2 finish in Helsinki, held off a brave challenge from Japan's Kenji Narisako to win in 48.24 seconds while Masahira Yoshikata was third.
American Dwight Phillips won the long jump, the two-time world champion prevailing with his first and only effort of 8.06 meters with Japan's Daisuke Arakawa and Shinichi Terano following in second and third.
