Amina Njonkou and Ramses Lonlack combined for 34 points as Cameroon secured at least a place at next year's FIBA Women's Olympic Qualifying Tournament (WOQT).
It was Cameroon's seventh win in as many games.
Stats Don't Lie: Two key Nigeria players, Ndidi Madu and Olayinka Sanni, fouled out midway through the fourth quarter, and Nigeria were never the same near the painted area.
Game Hero: Njonkou not only provided 14 crucial points, but she also dominated the paint with a game-high 16 rebounds.
Bottom Line: The result go either way, but Cameroon, boosted by a tireless supporting crowd, handled the game better in the final minutes, and will play the tournament final for the very first time.
Adaora Elonu who led Nigeria with 17 points said after the game: "A lot of things went wrong tonight. We weren't executing and they were scoring too many points. They were getting what they needed, and we let them have energy and feel from the crowd, which was bad for us."
