Japanese sensation Naoya Inoue became just the second man to be a two-division undisputed champion after claiming a 10th-round TKO victory over Marlon Tapales at the Ariake Arena in Tokyo.

Inoue (26-0, 23 KOs) joins Terence Crawford as having achieved the feat in the modern, four-belt era, having unified the four bantamweight belts in 2022 and now the super bantamweight WBC, WBO, IBF and WBA straps across two fights in 2023.

He has not fought a non-title fight since April 2013 and in late 2022 became the No.1-ranked pound-for-pound boxer by The Ring, now sitting No.2 behind Crawford.

Only Inoue, Crawford, Katie Taylor, and Claressa Shields have been undisputed champion in two divisions.

Tapales upset Murodjon Akhmadaliev in April to become champion on a controversial night where one of the three scorecards went 118-110 Akhmadaliev’s way.

The upset-minded Filipino certainly had his moments but was knocked down twice, in the fourth and 10th rounds, the latter ending the bout.

Australia’s Sam Goodman (17-0) is the No.1 contender in the division with the IBF and WBO and previously declared he wants a shot at the winner in 2024.

WBC mandatory challenger Luis Nery is rumoured to be on the cards for Inoue in May, with the Japanese confirming he is in negotiations for a fight at that time.
