World 100m silver medalist Christian Coleman (20) broke the 60m indoor world record when he clocked 6.34 seconds at the US Indoor Championships in New Mexico.

His mark beat the previous record of 6.39 set twice by fellow American Maurice Greene, in 1998 and 2001.

Coleman’s time is pending ratification by world governing body, the IAAF.

Coleman clocked 6.37 at a South Carolina meeting in January, 2018 but it was not ratified for technical reasons.

That time beat his previous best of 6.45, which he recorded when he won the US Indoor Championship last year.
