In the 82kg final, Geraei was not to be denied in his first chance at world gold, as he stormed to a 9-0 victory over a shell-shocked Erik Szilvassy from Hungary.
Geraei, normally a 77kg wrestler who was competing at the heaviest weight of his career, encountered no problems handling the extra bulk against Szilvassy, a winner of international tournaments this year in Zagreb and Budapest.
Geraei, who finished fifth at the Tokyo Olympics but missed the Paris Games due to a suspension, then completed a snap-down, go-behind takedown to finish the match in 1:35 and add the world gold to the bronzes he won at 71kg in 2017 and at 77kg in 2019 and 2021.
