Devin Haney was eager to step up and go to Australia to compete for the uncontested lightweight championship against George Kambosos Jr. on Saturday night

That proved to be a wise option for Haney, as he demolished Kambosos over 12 rounds to capture all four world titles at 135 pounds

Haney is only the sixth boxer in any weight class to unify all four recognised championships and the second youngest at only 23 years old

The fight had minimal drama, with Haney instantly developing a great jab that prevented Kambosos from launching his assault

As the jab connected, Haney unleashed lead left hooks and straight right hands after it, each strike preventing Kambosos from letting go with the right hand he appeared to have been loading up all night

After Kambosos' dramatic upset win against Teofimo Lopez to earn the WBC franchise championship while also holding the WBA, IBF, and WBO world belts, Haney was not the man initially planned to face him

Kambosos was supposed to defend against former champion Vasiliy Lomachenko

When Lomachenko withdrew from the fight to be in his native Ukraine following Russia's invasion, Haney had the chance to quiet detractors who said his WBC championship was illegal

When he was upgraded from an interim champion, Lomachenko was declared franchise champion by the WBC

Haney was excellent from the start, appearing every inch a superb boxer as he shut down Kambosos and marked up the Aussie's face with a steady diet of punches

Kambosos would have his revenge since the bout with Haney featured a rematch provision that required Haney to return to Australia if he won the first round
