Becoming undisputed lightweight champion was always among the goals set out by Devin Haney.

Merely winning all the titles was never the end game, though.

Las Vegas’ Haney is set for his sixth overall defense of the WBC title and first as the true lightweight king, as he faces Sydney’s George Kambosos Jr. The rematch takes place October 16 on ESPN from Rod Laver Arena in Melbourne, Australia, barely four months after the unbeaten American traveled Down Under to become the first undisputed lightweight champion in the four-belt era and—at age 23—the youngest at any weight to accomplish the feat.

“It was a dream come true for me to become undisputed and my name mentioned with the greats,” Haney noted during a recent press conference. “It doesn’t stop there. I want my name mentioned with the greats still.”

Haney (28-0, 15KOs) entered the fight as the WBC titlist, coming up big on the road as he soundly outclassed Kambosos (20-1, 10KOs) in a landslide win to claim the lineal/WBA/IBF/WBO titles as well. Scores of 116-112, 116-112 and 118-110 landed in favor of Haney, who became the first undisputed champ at lightweight in any era since the late, legendary Pernell Whitaker (40-4-1, 17KOs; 1NC) fully unified the division by August 1990.

Few undisputed champions have been able to keep together the titles, either vacating one by one or leaving the division entirely in search of a championship at the next weight. Whitaker didn’t stop after his 1st round knockout of Juan Nazario to win the WBA title and retain his WBC and IBF belts, adding three more title defenses with all the belts at stake before moving up for good in 1992.

That is the legacy Haney wants to leave behind while he can still make lightweight.

“I want my name to be mentioned with Pernell Whitaker,” Haney insisted. “He was undisputed at lightweight and he defended his belts as undisputed. I want to do the same thing. I want my name to be along those who defended the belts. I want to be the youngest undisputed to defend the belts and I will come out victorious. Inshallah.”
