Africa fastest man Ferdinand Omanyala on Sunday morning failed to qualify for the 100m final after finishing fifth in heat 3 of the semi-finals at the World Athletics Championships at Hayward Field, Oregon, United States.
The 26 year-old clocked 10.14 seconds in the semis, slower than his Heat 7 on Saturday morning when he clocked 10.10seconds to finish third.
Omanyala came fifth behind Jamaican Oblique Seville (9.09), American Marvin Bracy (9.93), Canadian Aaaron Brown (10.06 ) and Nigerian Oghene Ashe. (10.12)
Oblique Seville and Marvin Bracy topped the third heat and automatically qualified with the other top two finishers in each heat.
The first heat was won by South African Akani Simbine in 9.97, who beat American Trayvon Bromell with the same time.
Italian Olympic 100m champion Lamont Jacobs pulled out of the Heat after continuing to struggle with a thigh injury.
Jacobs, a massive underdog winner in Tokyo, has battled the injury for several weeks and looked uncomfortable in running 10.04 in his heat on Friday.
He was due to line up in the third of three semis on Saturday - with the final later in the evening - but tweeted: "A painful choice, I am forced to stop. I am a fighter and this is why I decided to be in Eugene.
"Now, in order not to compromise the rest of the season by risking a more serious injury, I have to postpone the challenge. I promise, I will do my best to make you dream."
