Devin Haney was crowned as the new undisputed lightweight champion by unanimous decision after the American star outclassed George Kambosos Jr in Australia.
Kambosos Jr headed into the bout - which took place in his home nation - with all the belts after his shock victory over Teofimo Lopez last year, but Haney produced a terrific performance to defend his WBC crown and claim the lineal, WBA, IBF and WBO titles from his lightweight rival, who suffered the first defeat of his 21-fight career at Marvel Stadium.
After 12 rounds, Haney was crowned as the new lightweight king after the fight was scored 116-112, 116-112 and 118-110 in the 23-year-old's favour. Haney maintains his perfect record and moves to 28-0 as a result of his clinical display.
