Koki Kameda stopped Humberto Pool in the fifth round Saturday in a warmup for his upcoming title bout against WBC flyweight champion Daisuke Naito.
Former WBA light flyweight champion Kameda deadened Pool with a stinging right body blow in the third round and sent his Mexican opponent to the canvas three times in the fifth with a flurry of punches at Differ Ariake.
The referee jumped in to stop the nontitle bout at 2 minutes, 29 seconds.
“I want to make solid preparations for the fight (against Naito),” said Kameda, who is aiming to capture world titles in two weight classes.
“He (Naito) is the world champion and defended the title five times so I know that he isn’t a weak opponent. I have to be focused,” said Kameda, the eldest of the three Kameda brothers.
The fight between Naito and Kameda, for which a date and venue have yet to be set, is being billed as an epic showdown after the champion defeated the second eldest brother Daiki in a wild affair in defense of his WBC crown in October 2007.
Daiki repeatedly resorted to foul play, leading to a one-year suspension of his boxing license, and lost the fight in landside decision. Koki, who was also reprimanded in the fiasco for encouraging his brother to fight dirty in his corner, has promised revenge.
