Okagbare will be running in her third semis since she made her debut in the event at the London 2012 Olympics. She ran 11.05 seconds to win her first-round heat.
The 32-year-old has been drawn in the first semi-final heat alongside two heavyweights of the event – defending champion Elaine Thompson-Herah of Jamaica who ran 10.82 seconds to win her first-round heat, and Great Britain’s Dina Asher-Smith, the 200m world champion two years ago in Doha, Qatar who ran 11.07 seconds to come second in her first-round heat.
Okagbare, 2008 Beijing Olympics Long Jump silver medallist, will be in action at exactly 11.15 am Nigerian time on Saturday.
Nwokocha, on her part, ran a new personal best of 11.00 seconds to secure her qualification to the semi-finals in her debut at the Olympics.
The 20-year-old has also moved into fifth in the Nigeria all-time list behind Okagbare (10.79), Glory Alozie (10.90), Mary Onyali (10.97), and Damola Osayomi (10.99).
The home-based athlete who posted 11.09 seconds to secure her qualification for the Olympics in March at the MOC Grand Prix in Lagos will, however, need to make further history by breaking the 11 seconds barrier as the fifth Nigerian woman to do so to stand a chance of joining Onyali and Okagbare as debutants who ran all the way to the final of the event.
She has been drawn to run from lane nine in the third semi-final heat with the fastest woman alive, Shelly-Ann Fraser-Pryce of Jamaica, as well as Daryl Neita of Great Britain, Teahna Daniels of the USA, and fellow African, Muriel Ahoure of Ivory Coast.
