Jamaica sprinter Usain Bolt displayed his supremacy as he defeated his American arch-nemesis Justin Gatlin again to win the 200m title for the fourth consecutive time at the World Athletics Championship in Beijing on Thursday.
The six-time Olympic champion clocked 19.55sec to win his 10th world Championship gold.
Reflecting on his performance, Bolt said that he feels happy to be a 10-time gold medallist especially when a lot of people have doubted him, the Guardian reported.
Controversial American sprinter Gatlin, who has served two doping bans, finished second in 19.74 sec, ahead of his South African fellow Anaso Jobodwana, who finished third in 19.87sec.
Earlier, Bolt had defeated Gatlin to claim 100m title.
Bolt and Gatlin will next meet again in the 400m relay on Saturday.
