Usain Bolt completed a double-gold with a victory in the men's 200 meters and the Russian women's relay team ended the United States' domination in the 4x400 on Saturday at the 2013 World Track & Field Championships.
Bolt won the 100 meters last Sunday and the Jamaican sprint star had little competition in capturing the 200 meters on Saturday. He cruised to the finish line in a time of 19.66 seconds for his third straight world title at the distance.
Warren Weir of Jamaica finished second Saturday in a time of 19.79 seconds, while American Curtis Mitchell took third at 20.04 seconds.
It's not an unfamiliar double for Bolt, who also completed the feat in the 2008 and the 2012 Olympics. He also won double-gold in the 2009 Worlds, but a false-start disqualification in the 100-meter final denied him the chance at double-gold two years ago at the Worlds in South Korea.
Bolt is expected to try for a third gold at the 2013 championships on Sunday as part of Jamaica's relay effort in the 4x100.
The U.S. women entered Saturday's 4x400 final with three straight world titles and five consecutive Olympic gold medals, but without an injured Allyson Felix came up short against the Russians. Felix tore her right hamstring Friday in the 200 meters.
Antonina Krivoshapka ran the anchor leg for the host nation and the Russian women finished with a winning time of 3 minutes, 20.19 seconds. The American team of Jessica Beard, Natasha Hastings, Ashley Spencer and Francena McCorory took silver, .22 seconds behind. Great Britain was third, another two seconds back.
American Brianna Rollins captured gold in the women's 100-meter hurdles, edging Olympic champion and defending world champ Sally Pearson of Australia by just 6/100ths of a second. Rollins finished in a time of 12.44 seconds.
Uganda's Stephen Kiprotich followed up his Olympic gold in the men's marathon with a world title on Saturday. He finished in a time of 2 hours, 9 minutes and 51 seconds, beating Boston Marathon winner Lelisa Desisa of Ethiopia by 21 seconds.
Ethiopia's Meseret Defar won Olympic gold in the women's 5,000 meters last summer in London and also captured the event Saturday, finishing in a time of 14 minutes, 50.19 seconds. Kenya's Mercy Cherono was more than a second behind.
Also Saturday, Russia's Svetlana Shkolina beat American Brigetta Barrett for the women's high jump title and Vitezslav Vesely of the Czech Republic claimed gold in the men's javelin.
