Bolt beat Justin Gatlin by one hundredth of a second to retain the 100m title
at the World Athletics Championships in Beijing.
Bolt had stumbled out of
the blocks in winning his semi-final but found a season's best run of 9.79
seconds to win the title for the third time. Gatlin, 33, had been unbeaten in 28 races and started as favourite after running 9.77secs in his semi-final.
But Bolt, 29 had a much better start in the final and won his ninth world gold.
America's Trayvon Bromwell and Canada's Andre De Grasse were both awarded a bronze medal after clocking identical times of 9.911secs.
