American David Oliver won gold in the men's 100-meter hurdles at the 2013 World Track & Field Championships, while countrymate Carmelita Jeter came up short in the women's 100 meters.
Oliver led a U.S. 1-2 result in the hurdles, finishing in a time of 13.00 seconds. Ryan Wilson was .13 seconds behind and Russia's Sergey Shubenkov denied an American sweep by edging Jason Richardson for the bronze by just 3/100ths of a second. Richardson won silver at the Olympics last summer.
Olympic champion Aries Merritt of the United States was sixth.
Jeter was the silver medalist for the 100 meters in London last summer, finishing 3/100ths of a second behind Jamaica's Shelly-Ann Fraser-Pryce, who captured gold again on Monday.
Fraser-Pryce finished Monday in a time of 10.71 seconds, but Jeter had to settle for bronze this time. Murielle Ahoure of the Ivory Coast took silver at 10.93 seconds, just 1/100th of a second faster than Jeter.
The women's 400 meter title went to Great Britain's Christine Ohuruogu in as tight a finish as can be imagined. The London silver medal winner and 2008 Beijing Olympic gold medalist at the distance crossed the line first on Monday with an official time of 49.41 seconds, just in front of Botswana's Amantle Montsho, who was 4/1000ths of a second behind.
Valerie Adams of New Zealand won the women's shot put. The reigning two-time Olympic champion's best throw Monday was 20.88 meters, earning her a fourth straight world championship gold. She was awarded gold in London last year after Nadzeya Ostapchuk of Belarus failed a drug test.
Germany's Raphael Holzdeppe claimed gold in the men's pole vault. Holzdeppe, last year's Olympic bronze medal winner, and Olympic champion Renaud Lavillenie of France each finished at 5.89 meters, but the German earned the gold because he had fewer misses.
Poland's Pawel Fajdek won the men's hammer throw with a first-throw distance of 81.97 meters, bettering Olympic champion Krisztian Pars of Hungary's top mark of 80.30.
