The Democratic Republic of the Congo-born athlete achieved his goal of making it to the second stage after he ran in some style to set a new personal best time of 10.33 in the preliminary rounds.
It was a valiant effort in the heats by the refugee athlete but a stacked field including Trayvon Bromell of the U.S. and Zharnel Hughes of Great Britain, meant Keletela missed out on tomorrow's semi-finals.
Escaping from war
Keletela, 22, was born in the Democratic Republic of the Congo.
After losing both of his parents to conflict in his homeland, he decided to move to Portugal five years ago with his aunt.
After a year in refugee centres he was granted asylum.
Now he races for the famous Sporting Clube De Portugal in Lisbon, where he is trained by his hero Francis Obikwelu.
The Athens 2004 silver medallist represented Portugal after arriving from Nigeria at 16, and still jointly holds the European record of 9.86.
With a new personal best reached on the world's greatest sport stage Keletela can walk away from Tokyo 2020 with his head held high, and in the knowledge there is certainly more to come.
