Inoue still hungry after becoming undisputed champ in second weight class

TOKYO – Japan's Naoya Inoue said he was still as hungry as ever after becoming an undisputed world champion in a second weight class on Tuesday, knocking out Marlon Tapales to claim all four super bantamweight belts.

The unbeaten Inoue, nicknamed "Monster", floored the fighter from the Philippines with a huge right hand in the 10th round in Tokyo to add the WBA and IBF titles to his own WBC and WBO belts.

Inoue finally ended Tapales's challenge with a ferocious right hand that his opponent never looked like getting up from.

Inoue said Tapales was a "very tough" fighter who surprised him with his strong defense.

"He kept a poker face throughout and didn't show that my punches were doing him any damage, so I was quite surprised when he went down in the tenth round," he said.

Tapales upset Uzbekistan's Murodjon Akhmadaliev by split decision in April to win the IBF and WBA titles.

He vowed to come back from the loss but conceded that the result was a fair one.

"I was impressed by Inoue's technique as a boxer, and I was surprised by his speed," said Tapales, whose record dropped to 37-4 with 19 KOs.

"He was very
