TOKYO – Japan’s undisputed super-bantamweight world champion Naoya Inoue said an early scare got him “fired up”, after he stopped Mexico’s Luis Nery in the sixth round to retain his titles at the Tokyo Dome on May 6.

Around 43,000 fans packed into the famous venue for the first boxing match there since underdog James “Buster” Douglas knocked out unbeaten heavyweight champion Mike Tyson in February 1990 – in one of the sport’s biggest upsets.

Another seismic shock looked like it could be on the cards when Nery floored the unbeaten “Monster” Inoue in the first round with a huge left hand, with all four championship belts – International Boxing Federation, World Boxing Association, World Boxing Council and World Boxing Organisation – up for grabs.

But the Japanese got up and knocked his opponent down in the following round, before sending him to the canvas again in the fifth and finishing him off with a right hook in the sixth.

“It was a great feeling to knock him down, but how about that surprise in the first round?” said the 31-year-old Inoue.

“As a boxer, when that happens to you it fires you up. It gave me a lot of energy.”

He chuckled incredulously to himself as he sat down at the end of a stunning first round.

But he then gave a yell as he left his stool for the start of the second and was soon on level terms after dropping Nery with a well-timed left.

“From the moment I went down, I was able to recover calmly,” he added.

“I think it was precisely because I went down that I was able to fight the way I did.”

Inoue gave yet another demonstration of his ferocious punching power as he picked Nery apart in the following rounds.

He downed his opponent with a juddering left hook in the fifth, then landed the finishing blow in the sixth to win by technical knockout.

Inoue took his record to 27-0 with 24 wins by KO, and said that his team would enter negotiations to fight Australian Sam Goodman in his next title defence, likely to be in September.

He also said the fight had been a “great experience”.

“Fighting at Tokyo Dome gave me a lot of power, but there was also pressure,” he said.

It was his first title defence since becoming the undisputed super-bantamweight world champion in December.

He is just the second man to become undisputed world champion at two different weights since the four-belt era began in 2004. American Terence Crawford was the first. AFP
