By winning the belt in only his 10th professional fight, Usyk, the 2012 Olympic heavyweight gold medalist for Ukraine, broke the division record for fewest fights needed to win a world title, surpassing the mark held by Evander Holyfield, who won a cruiserweight world title in his 12th fight by outpointing Hall of Famer Dwight Muhammad Qawi in an epic 15-rounder in 1986.
