WBO bantamweight titleholder Tomoki Kameda has signed with powerful adviser Al Haymon, the boxer confirmed to RingTV.com on Wednesday.

In his last fight on Saturday, on the undercard of Saul Alvarez’s split decision over Erislandy Lara at the MGM Grand in Las Vegas, Kameda (30-0, 19 knockouts) used a left hook to the body to drop and stop Pungluang Sor Singyu at the 1:35 mark of the seventh round. Kameda won what represented his American debut against Pungluang (46-3, 31 KOs), who was knocked out for the first time in his career.

“It’s time to move on with my career now that I’ve signed with Al Haymon. I just fought a very, very tough opponent who came to fight and to go the distance but I was looking to stop him and to look impressive,” said Kameda, 23, through translation by camp member Luis DeCubas Jr.

“I was able to get him with a perfect left hook to the body and I believe that I demonstrated my talents and my abilities and that’s what impressed everyone. Now it’s time to get the bigger fights. I’m really excited. I just fought for the first time in America in Las Vegas, which went great.”

In aligning with Haymon, Kameda follows moves made earlier this year by RING light heavyweight champion Adonis Stevenson, IBF junior lightweight titleholder Rances Barthelemy, IBF 140-pound titleholder Lamont Peterson, lightweight Anthony Peterson, ex-RING 175-pound champ Chad Dawson and former titleholders Amir Khan, Robert Guerrero and Luis Collazo.

The recipient of the 2013 Cus D’Amato “Manager Of The Year” award by the Boxing Writers Association of America, Haymon’s stable includes Floyd Mayweather Jr., Marcos Maidana, Adrien Broner, Lucas Matthysse and Lara among many others.

Kameda also addressed a report by FightHype.com that his siblings, Koki and Daiki have signed with Haymon. He said they are not signed but indicated that they may be considering it.

Koki, 27, was the WBA 118-pound titleholder until he vacated in December in order to move down to flyweight and Daiki, 25, was the IBF junior bantamweight titlist until he lost by decision top Liborio Solis last December.

“Once they do sign or do not sign, you guys will be the first to know,” said Tomoki Kameda. “My two brothers are in Japan,and, obviously, their dream is to come to the United States as well and to fight here. Right now, at this moment, I’m the one who has signed with Al. But anything is possible.”
