USAIN BOLT PRODUCED a stunning second 50 metres to pip Justin Gatlin for World Championship gold.
Bolt finished in a time of 9.79, just one-hundredth of a second ahead of the American silver medalist.
In an extremely tight contest behind the two favourites, USA and Canada forced a dead heat for third place and so Trayvon Bromell and Andre De Grasse both come away with bronze and a time of 9.92 seconds.
In the semi-final, defending champ Bolt rode through a terrible start to turn on the power in the final 40 metres and clock 9.96 seconds, with De Grasse second on the same time.

Gatlin, who has twice served bans for doping, had no such problem in the second heat, winning in a blistering time of 9.77 ahead of compatriot Mike Rodgers, who has also served a drugs suspension. Neither men managed to improve on that semi-final marker.
