The US sprinter becomes only the second athlete in history to clock sub-10 seconds for 100m, sub-20 for 200m and sub-44 for 400m

Michael Norman stormed to a world-leading 100m PB of 9.86 (+1.6m/sec) in Fort Worth, Texas, on Monday to become just the second athlete in history to run sub-10 seconds for 100m, sub-20 for 200m and sub-44 for 400m.

South Africa's Wayde van Niekerk became the first to achieve the feat when he clocked 9.98 in Bloemfontein in 2016.

The USA's Norman, who won the 2016 world junior 200m title and is now more known as a 400m sprinter, adds his new 100m time to his 200m best of 19.70 recorded in Rome last year and his 400m PB of 43.45 from California, also set last year.

"After four long years I finally got to run the 100m," 22-year-old Norman wrote on Twitter, with his previous best of 10.27 having been set during his last race over the distance in 2016.

In his post Norman also highlighted the performance of his training partner Rai Benjamin, who despite being a 400m hurdler clocked a 100m PB of 10.03 to finish second in the race.

The world silver medallist became the joint third-fastest ever 400m hurdler last year when he clocked 46.98 in Zürich.

Benjamin also has a 200m PB of 19.99 set in Paris in 2018 and a 400m best of 44.31 from California last year.

Also in Fort Worth, Olympic 100m hurdles champion Brianna Rollins-McNeal broke the 150m world best with 16.41 (+1.1m/s), improving the time of 16.46 run by Merlene Ottey in 1989.
