( CNN ) -- Once Usain Bolt got out of the starting blocks , no one was going to beat him at the world championships . Two years ago at the worlds , the Jamaican false started in the 100-meter final and was disqualified . His countryman and training partner , Yohan Blake , took advantage to claim gold in Daegu , South Korea . There was no false start for Bolt on Sunday in rainy Moscow and he captured his second world title in the 100 meters . His time of 9.77 seconds was well off his world record of 9.58 seconds but still good enough to comfortably beat American Justin Gatlin and Jamaican Nesta Carter . Bolt now owns six world championship gold medals to go along with six gold medals at the Olympics . `` I am happy but I wanted to do better , '' Bolt was quoted as saying by the BBC . `` My legs were sore after the semifinals . '' Perhaps mindful of what happened in South Korea , Bolt 's start was cautious and Gatlin led him early . But after getting fully into his stride , Bolt -- despite not feeling at his best -- eased past Gatlin and coasted home . Gatlin finished in 9.85 seconds and Carter in 9.95 . `` I thought I had it for a second but then I saw these long legs coming on my right side , '' Gatlin told reporters . Bolt last year called himself a `` living legend '' and the result in Moscow on Sunday wo n't diminish his confidence . It likely also lifted Jamaican sport . Jamaica was left reeling when two-time 200-meter Olympic champion Veronica Campbell-Brown , former 100-meter world-record holder Asafa Powell and Olympic relay gold medalist Sherone Simpson tested positive for banned substances before the world championships . Then last week , soccer 's FIFA announced that a Jamaican international tested positive for a banned substance , without naming the player . Besides Powell , Campbell-Brown and Simpson , American Tyson Gay failed a drug test and ruled himself out of the world championships in July . With sprinters thus under scrutiny , Bolt spoke up in July and said : `` I know I am clean . '' Without Gay -- who owned the two fastest times in the 100 meters this year prior to Moscow -- and the injured Blake , Bolt 's task was made easier in Russia , although Gatlin defeated Bolt in Rome in June . Gatlin has served a four-year ban for doping . Bolt took center stage but he was n't the only standout to win another world title Sunday . Ethiopia 's Tirunesh Dibaba collected her third in the 10,000 meters , an event she 's won twice at the Olympics .
Usain Bolt wins the 100 meters at the world championships in a time of 9.58 seconds . Bolt reclaims the world title after being disqualified from the 2011 final due to a false start . Jamaican Usain Bolt took the silver and South Korea 's Justin Gatlin claimed bronze .
