First undisputed super-middleweight boxing champion

The first undisputed super-middleweight boxing champion is Saul “Canelo” Álvarez (Mexico), who defeated Caleb Plant on 6 November 2021 to hold the WBA, WBO, WBC and IBF belts all at the same time. He also holds The Ring super-middleweight belt.

The current super-middleweight division, in which fighters can weigh a maximum of 168 pounds, began with the first IBF title fight in 1984. Álvarez defeated Plant with an 11th-round TKO at the MGM Grand Garden Arena in Las Vegas, Nevada, USA. He is only the sixth male fighter to become undisputed world champion in the four-belt era (after Bernard Hopkins, Jermain Taylor, Terence Crawford, Oleksandr Usyk and Josh Taylor).
