Abderrahman Samba ran the second fastest 400m hurdles ever in Paris on Saturday evening.
The 22-year-old Qatari hurdler crossed the line at the Charléty Stadium Diamond League meeting in a time of 46.98. It's just the second time ever that anyone has run under 47 seconds.
Only Kevin Young, when running his world record of 46.78 at the Barcelona Olympics in 1992, has ever gone faster.
Samba, who finished seventh in World Championship final last year, now holds the world leading time for 2018. Last month at the NCAA Championships, 20-year-old Antiguan, Rai Benjamin, ran 47.02. That is now the joint third fastest time ever for the event following Samba's run.
