1 Canelo Álvarez (four divisions)
Having started his professional career at the age of 15 (at junior-welterweight), it should come as no surprise that Álvarez has soared through the weight divisions. However, it remains no less impressive that he has been able to win world titles at super-welterweight, middleweight, super-middleweight and light-heavyweight.
2 Naoya Inoue (four divisions)
While some will argue it is easier to jump weight classes and accumulate titles in the lower divisions, take nothing away from Inoue’s ability to win belts in four of them. His first arrived at light-flyweight, while his last was secured at super-bantamweight the night he stopped Stephen Fulton in seven rounds.
3 Román González (four divisions)
Known as “Chocolatito”, Nicaraguan legend González has competed 55 times as a professional and during the course of these 55 fights won world titles in four weight classes. His journey began at minimumweight, where he won and defended the WBA belt, before it then took him to light-flyweight, flyweight and super-flyweight, all divisions in which he also won titles.
4 Terence Crawford (three divisions)
Crawford recently confirmed his dominance in yet another weight class when beating Errol Spence inside nine rounds in July. With that win, he found himself on top of the welterweight division, just as he had previously found himself on top of both junior-welterweight and lightweight divisions.
5 Vasiliy Lomachenko (three divisions)
Ukrainian wizard Lomachenko won his first belt in pro fight number three, when outpointing Gary Russell Jnr. That was at featherweight, of course, but it wouldn’t take long for Lomachenko to also win belts at super-featherweight and lightweight, the division in which he truly announced himself as number one.
6 Emanuel Navarrete (three divisions)
Stubborn and relentless, Navarrete won his first WBO belt at junior-featherweight, beating Isaac Dogboe over 12 rounds. He then won the featherweight belt two years later, before beating Liam Wilson for the super-featherweight version earlier this year.
7 Oleksandr Usyk (two divisions)
Not content with being the clear number one cruiserweight in the world, Usyk packed on some additional muscle and ventured to heavyweight in 2019. There, he would twice defeat Anthony Joshua to take his belts, all of which he then successfully defended against Daniel Dubois in August.
8 Teofimo Lopez (two divisions)
In just 20 pro fights Lopez has managed to claim a host of belts at both lightweight and super-lightweight. His big win at lightweight was against Vasiliy Lomachenko, whom he outpointed in 2020, while his big win at super-lightweight came in June of this year when he dethroned Josh Taylor.
9 Juan Francisco Estrada
Despite losing his first world title shot in 2012, Estrada has since flourished in not one but two weight classes: flyweight and super-flyweight. He made five defences of the WBA and WBO belts in the former and made three defences of the WBC belt in the latter.
10 Shakur Stevenson (two divisions)
On November 16 in Las Vegas, Stevenson enters his third weight class (lightweight) with every intention of picking up another belt. However, for now he has struck gold in two weight classes: featherweight and super-featherweight. His reigns in both were fleeting to say the least.
