Terence Crawford
Taylor faced WBC and WBO champion José Ramírez on 22 May 2021, at the Virgin Hotels Las Vegas in Paradise, Nevada, for the undisputed light-welterwight title. Taylor knocked his opponent down twice in the sixth and seventh rounds, both times with his left hand, en route to a unanimous decision victory with all three judges scoring the bout 114–112 in his favour. The result meant that Taylor became the second Scotsman to be an undisputed champion (after Ken Buchanan); the first British fighter to become an undisputed champion in the four-belt era; and only the fifth man to do so after Bernard Hopkins, Jermain Taylor, Terence Crawford and Oleksandr Usyk.
