OSAKA – Koki Kameda retained the WBA bantamweight title in his first defense of the crown with an 11th-round, technical knockout of Daniel Diaz of Nicaragua on Saturday night in Osaka.
Kameda had Diaz on the ropes for most of the affair, unraveling his decidedly weak opponent with a sharp left jab in front of his home fans at Osaka Prefectural Gymnasium.
The Japanese southpaw improved to a 25-1 record, including 16 knockouts. Diaz, who was fighting in his first world title match, fell to 18-3 (13 KOs).
Kameda floored Diaz with a left in the eighth and sent his opponent’s mouthpiece flying across the ring with another stinging blow to the jaw in the ninth.
Diaz continued to flounder about like a drunken sailor as he was tagged by a series of lefts in the 11th, and the referee called an end to the match after the round concluded.
Kameda’s solid defense was enough to carry him, although Diaz, who has the longer reach, did force his way to occasionally send the Japanese fighter retreating to no serious detriment.
The eldest of three boxing brothers, Kameda became the first Japanese to win titles in three weight categories when he defeated Alexander Munoz of Venezuela by unanimous decision last December.
