Hard-hitting Mexican Jhonny Gonzalez (48-7, 42 KOs), 124,75, captured the WBC feather belt as he stunned the audience with a one-punch stoppage of defending champ Hozumi Hasegawa (29-4, 12 KOs), 125.75, at 0:58 of the fourth session on Friday in Kobe, Japan.

Hasegawa, a Japanese southpaw who previously kept his WBC bantam throne ten times to his credit, moved up to the feather category and acquired the WBC belt by unanimously decisioning Juan Carlos Burgos of Mexico last November.

It was his first and mandatory defense against the official challenger Gonzalez, ex-WBO 118-pound ruler who lately registered seven consecutive stoppages after suffering a bad TKO defeat by Toshiaki Nishioka in three rounds in Mexico in May 2009.

WBC super-bantam champ Toshiaki Nishioka (38-4-3, 24 KOs), 121.75, scored his sixth defense when he patiently outjabbed and outpunched Mauricio Munoz (21-3, 9 KOs), 121, finally catching the game challenger with a smashing left en route to a spectacular knockout at 3:07 of the ninth round in the second of the triple-header on Friday in Kobe, Japan.

WBC super-feather champ Takahiro Aoh (21-2-1, 10 KOs), 130, a Japanese southpaw, looked impressive in successfully making his initial defense as he outhustled ex-WBC interim ruler Humberto Gutierrez (28-3-1, 20 KOs), 130, Mexico, from the outset, entirely controlled the bout with effective combinations and finally sank him with a single vicious right hook to the belly at 1:06 of the fourth round on Friday in Kobe, Japan.

It was the first of the WBC world title triple-header and an encounter of pugnacious southpaws, which fully entertained the sell-out crowd at the World Memorial Hall. Aoh, who had dethroned German Vitaly Tajbert via unanimous nod here last November, took the inititative with a good attack, pressing the action from the first round. Aoh, formerly six-time national amateur high school champ, steadily piled up points as he gamely mixed it up and had the upper hand over the taller but slower Mexican hombre.
