Devin Haney ended George Kambosos’ unbeaten streak and became the undisputed lightweight world champion at Melbourne’s Docklands Stadium in the early hours of Sunday morning.
Haney added Kambosos’ WBA, IBF, WBO and The Ring belts to the WBC strap he already held as the American controlled the fight in front of 41,129 fans to become the first undisputed champion at the weight since the start of the four-belt era.
"This is a dream come true," said Haney, who took his record to 28-0.
"I was comfortable. I was sticking to the game plan, the game plan was to go in and hit and not get hit and I did that for the majority of the fight.
"I took the last round off because I knew I was comfortably ahead, but I fought a good, smart fight."
Kambosos, who became world champion when he scored a surprise win over Teofimo Lopez last November, threatened to ignite a cautious opening round with a late flurry of punches.
Haney, though, was unflustered by the Australian’s attempts to impose himself, using his jab to steadily gain control of the fight and Kambosos’ face started to mark up under the eyes by the halfway point.
The American was pushed to the canvas during the eighth and Kambosos upped his tempo in the next round but, with his opponent continuing to prove elusive, the home boxer grew increasingly frustrated.
Kambosos was unable to make much of an impression on the 23-year-old, however, and in the end the judges handed Haney a comfortable margin of victory, with two judges scoring the bout 116-112 and the other giving the American a 118-110 win.
"I want to take the best test, the hardest test and I’m going to give him full respect for his victory and let him have his time," said Kambosos, who lost for the first time in 21 fights.
"We’ll do it again. I have to implement a few things but I thought the fight was very close.”
