Christian Coleman demonstrated just why he is the man tipped to lead sprinting into the post-Usain Bolt era when he roared to victory in the 60 metres at the world indoor championships on Saturday.

The 21-year-old U.S sprinter, who set a world record of 6.34 seconds last month, proved to be in a different league to his rivals as he triumphed in a championship record 6.37 seconds, equalling the second fastest run of all time which he had also set in January.

Su Bingtian, of China, took the silver in an Asian-record 6.42 with Coleman's U.S. team mate Ronnie Baker winning the bronze in 6.44.

Coleman, who lost only to compatriot Justin Gatlin in last year's 100 metres in London, was never beaten by the great Jamaican Bolt in their three meetings.

Coleman had looked magnificent in winning his semi-final in 6.45 seconds and suffered only one setback all day when he stumbled on the third step of his morning heat before easing to victory in a modest 6.71 seconds.
