Devin Haney respects George Kambosos Jr. and what he accomplished by beating Teofimo Lopez.

The unbeaten WBC world lightweight champion doesn’t think nearly as highly of Rolando Romero. Haney questions how Romero even ascended to the top spot in the WBA’s 135-pound rankings, which assured him of his upcoming shot at Gervonta Davis’ WBA world lightweight title.

Baltimore’s Davis (26-0, 24 KOs) and Romero (14-0, 12 KOs), of North Las Vegas, Nevada, will meet in a Showtime Pay-Per-View main event May 28 at Barclays Center in Brooklyn. Haney broke down during an interview with BoxingScene.com why he believes Davis will have his way with Romero in their 12-round, 135-pound grudge match.

“I think ‘Tank’ will win,” said Haney, who will battle Kambosos on June 5 at Marvel Stadium in Melbourne, Australia. “I think Rolly’s trash. I don’t rate him at all. I mean, who has he beat to prove he even belongs at the top? … What did he even do to get there? Who did he beat?

“His biggest fight that he won for the interim belt was against a guy that he really lost to. So, I mean, all that speaks for itself. ‘Tank’ is on a totally different level than Rolly, so I don’t even rate that fight at all. That’s not even a competitive fight to me.”

Las Vegas’ Haney referred to Romero’s highly questionable 12-round, unanimous-decision victory over Jackson Marinez in August 2020. The Dominican Republic’s Marinez seemed to out-box the hard-hitting Romero in that bout, but Romero won by scores of 118-110, 116-112 and 115-113.

Romero won the WBA interim lightweight title that night, but the WBA eliminated all of its interim championships last August in the embarrassing aftermath of the Gabriel Maestre-Mykal Fox scandal.

Davis isn’t the WBA’s legitimate lightweight champion, either. That distinction belongs to Kambosos, who won the WBA “super” lightweight title, along with the IBF, WBC franchise and WBO belts, from Lopez (16-1, 12 KOs) on November 27 at Madison Square Garden’s Hulu Theater in New York.

Sydney’s Kambosos (20-0, 10 KOs) will defend his IBF, WBA and WBO crowns against Haney (27-0, 15 KOs) in a fight ESPN will televise the night of June 4 in the United States. Barring a draw or no-contest, the winner will become boxing’s first fully unified lightweight champion of the four-belt era.
