American world 100m silver medallist Christian Coleman broke the 60m indoor world record, clocking 6.37 seconds at a meeting in Clemson, South Carolina.

Reports say Coleman’s mark beat the previous record of 6.39 set twice by fellow American Maurice Greene in 1998 and 2001.

The performance is subject to ratification by athletics’ world governing body the IAAF.

The 21-year-old Coleman is in his first full year as a professional athlete.

It beats his previous best of 6.45, which he recorded when he won the US indoor championship last year.

Coleman ran 9.82 seconds, the fastest 100m of 2017, at the US outdoor collegiate title meeting.

Expected to be America’s next great sprinter, he finished behind Justin Gatlin and ahead of world record holder Usain Bolt in the 100m at last year’s world championships in London.

The 2018 World Indoor Championships take place in Birmingham from March 1 to 4.
