To win the undisputed lightweight title, Devin Haney was willing to fly to Australia on Saturday night.

As a result, Haney won all four world titles at 135 pounds after dominating Kambosos across 12 rounds.

By only 23 years old, Haney becomes the ninth person to win all four recognized titles at any weight class.

Haney established a powerful jab early on that prevented Kambosos from ever getting his offense going.

Following Kambosos' jab, Haney fired lead left hooks and straight right hands to deter his right hand. By doing this,... 

...he prevented Kambosos from letting go with the hand he'd been loading up with the whole night.

With the official scorecards reading 116-112, 116-112 and 118-110, Haney won by unanimous decision.

It was impossible to land Haney's overhand right and big left hook, which Haney wanted to do.

I fought both ways. Whenever I walked to the left, I fought his right hand. Then I turned around and fought his hook.

Kambosos won the WBC title against Hayey after a shocking upset victory over Teofimo Lopez to win the title...

...Kabosos can exact revenge on Haney as his fight agreement with Haney included...

...a rematch clause which stipulated Haney must return to Australia should he defeat Kambosos in the first bout.

After the fight, Kambosos made it clear that he had every intention of activating that clause.Kambosos said he would respect him,... 

Though I thought the fight was close, I will not ruin his moment. I look forward to seeing him soon.
