Saul 'Canelo' Alvarez prevailed on points against Daniel Jacobs in Las Vegas to add another belt to his collection.
Canelo, who signed the richest contract in sports when he penned a 5-year, 11-fight, $365 million deal with streaming service DAZN in October, successfully defended his WBA 'Super' and WBC belts while also claiming Jacobs' IBF title in the Cinco de Mayo clash.
The highest-paid boxer in the sport and easily one of the best pound-for-pound fighters in the business, Canelo went into the bout as the overwhelming favourite.
But Jacobs, aptly nicknamed 'the Miracle Man after being told he would never box again when he was diagnosed with a rare form of bone cancer, in 2011, produced a brilliant showing and took the Mexican to the very limit in the champion-vs-champion fight.
However, Canelo's class saw him pick up the unanimous decision victory.
What next for Canelo? There's the option of going up against WBO champion Demetrius Andrade and trying to unify the division, while there's still still huge scope for a third bout with Gennady Golovkin, who was sat ringside at the T-Mobile Arena.
