In the final half, Odongo returned to torment the South African backline again, this time in the left wing as he paced through to score an unconverted try that tied the scores at 12-12 with three minutes left to play.
John Okoth would score the winning try with under a minute left on the clock as Kenya picked a historical 17-12 win.
Odongo finished the tournament with seven tries on his first outing with Shujaa. The Daystar University player scored three tries during the preliminary stages before scoring in the quarterfinals, semis, and a brace in the finals.
The win means Kenya is through to the Paris Olympics set for next year. South Africa will drop to the Olympic Repechage where they will be fighting for the final and 12th spot in Paris.
Additionally, Kenya will be joined by bronze medalists Uganda to fight for a place in the 2024-2025 World Rugby Sevens. They will play in the qualifiers dubbed Challenger Series.
