World Boxing Organisation bantamweight champion Tomoki Kameda of Japan has beaten Namibian challenger Immanuel Naidjala on a 3-0 decision to retain his title in Osaka.
Judges scored the 12-round title match 117-111, 118-110, 119-109 in favour of the 22-year-old Japanese, who nonetheless failed to live up to his overnight promise that he would finish off Naidjala in six rounds.
There was no knockdown in the fight between the two hitherto unbeaten boxers at the Osaka Bodymaker Colosseum.
It was 22-year-old Kameda's first defence of the title that he won by beating Namibian Paulus Ambunda on August 31 in the Philippine city of Cebu.
The two boxers exchanged fast punches early on, but Kameda got the upper hand after waging a fight at close range in the third round.
"I feel happy to have won the fight. I was quite confident this time but I could not fight in my style of boxing," said Kameda whose unscathed record stretched to 29 wins, 18 by knockout.
"I want to fight better next time."
For the 29-year-old Namibian, the sixth WBO contender, it was his first loss in a career studded with 17 wins, 11 of them inside the distance, and one draw.
