Egyptian duo Omar Assar and Dina Meshref did not drop a game as they secured Africa's sole mixed doubles table tennis place at Tokyo 2020.
Having both already qualified for singles and doubles events, the pair completed their hat-tricks in style in Tunis.
The Egyptians first beat Ahmed Djamal and Rahma Houssein of Djibouti 11-4, 11-2, 11-2, 11-2 in the quarter-finals.
A win against Thameur Mamia and Fadwa Garci of hosting Tunisia followed, with the final score 1-6, 11-6, 11-8, 11-2.
Nigeria's Segun Toriola and Olufunke Oshonaike awaited in the final, a day after Oshonaike booked an Olympic spot in the women's singles competition.
Assar and Meshref were too strong, winning 11-6, 11-6, 11-7, 11-2.
For the first time since 1992, Segun Toriola will not appear at the Olympics following a 4-0 (11-6,11-6,11-6,11-2) loss to Assar and Meshref in the mixed doubles final. #Rise2Tokyo pic.twitter.com/yl84eShwME— ITTF-Africa (@ITTFAfrica) February 29, 2020
Toriola, 45, had been hoping to qualify for his eighth Olympic Games and said afterwards that he would not attempt to reach Paris 2024.
He is, however, "satisfied with my career as it has been fantastic."
