The win at the Pavilhao Multiusos de Luanda marked D’Tigers’ second consecutive triumph in Group B, following their 77-59 victory over Madagascar in the opening game.
The Nigerians widened the gap to 68-47 in the third quarter and never looked back, sealing a 21-point win to stay top of their group.
The defeat extended Tunisia’s poor run in the competition, with the three-time champions missing key veterans Makram Romdhane and Radhouane Slimane. Their reliance on Jawhar Jawadi was not enough to stop Nigeria from recording a comfortable win.
The victory keeps alive Nigeria’s push for a second AfroBasket title, ten years after their first in 2015. Ironically, Tunisia’s last defeat at the tournament before this year also came against Nigeria during the 2015 edition.
D’Tigers will face Cameroon in their final group game on Sunday, a clash expected to decide who finishes top of Group B, as both sides currently boast perfect records.
