( CNN ) -- Usain Bolt has won a third consecutive world 200m title at the world championships in Moscow . The Jamaican sprinter powered home in a time of 19.66 seconds at the Luzhniki stadium to take his tally of world championship gold medals to seven . His compatriot Warren Weir took the silver in 19.79 seconds while U.S. sprinter Curtis Mitchell claimed the bronze in a time of 20.04 seconds . Bolt may not have been at his blistering best at these championships but has still put clear daylight between himself and his fellow sprinters when it matters most . The 26-year-old was run close by South Africa 's Anaso Jobodwana in Friday 's 200m semifinal but effortlessly stepped up a gear in the final . Running in lane four , Bolt powered around the bend leaving the field trailing in his wake . Weir chased gamely and was closing on Bolt as he crossed the line but the result , as always , was never in doubt . Bolt will look to add a eighth gold medal to his world championship collection on Sunday when he goes in the 4x100m relay . Six other gold medals were up for grabs on Saturday with Russia having a good day both on the track and in the field . Svetlana Shkolina won the women 's high jump for Russia going clear at 2.03 meters to beat U.S. rival Brigetta Barrett ( 2.00m ) who took silver . Shkolina 's teammate Anna Chicherova shared bronze with Spain 's Ruth Beitia . Russia 's women also pipped the U.S. to gold in the 4x400m relay as Antonina Krivoshapka held off a challenge from Francina McCrory of the U.S. on the anchor leg . Great Britain and Ireland took the bronze . But there was better news for the U.S. in the 100m hurdles with Brianna Rollins recovering from a poor start to take gold in 12.44 seconds ahead of 2011 world champion Sally Pearson from Australia . Great Britain and Ireland 's Tiffany Porter took bronze . In the men 's marathon , Stephen Kiprotich added world gold to the Olympic title he won in London last year .
