Though the challenger gave a spirited effort, WBC super bantamweight titlist Toshiaki Nishioka retained his belt with a win over Rendall Munroe today in Tokyo. Nishioka won on unanimous scores of 119-109. Bad Left Hook scored it 118-110 for Nishioka.

Nishioka (37-4-3, 23 KO) battered Munroe (22-2, 9 KO) with body shots, and rocked the Leicester native with head shots a few times over the course of the bout. But Munroe gave his all through all 12 rounds. It was a wide losing effort, but he was right there hanging with Nishioka throughout. The simple fact is, he was just the lesser man against the very talented Nishioka, who keeps his win streak alive. His last loss came in 2004.

On the undercard, Roman Gonzalez (27-0, 23 KO) stopped Francisco Rosas in two rounds. Rosas gave Gonzalez a tougher fight in 2009, losing a majority decision, but "El Chocolatito" was sharp shooting in the rematch. He just overpowered and overwhelmed Rosas to claim an interim title at 108 pounds.

Also, Jorge Linares (30-1, 19 KO) beat up on Jesus Chavez (44-8, 30 KO) through four rounds, with Chavez retiring with a shoulder injury. And Yoshihiro Kamegai (17-0, 15 KO) stopped Jose Alfaro (24-7, 21 KO) in six rounds.
