Rigondeaux stops Kokietgym

Junior featherweight champion Guillermo Rigondeaux defended his titles by knocking out Sod Kokietgym at 1:44 minutes into the first round at the Cotai Arena in Macao, China on Saturday.

Rigondeaux (14-0, 9 KOs) sent Kokietgym to the canvas with a right hook to the head, followed by a left cross.

Moments before the knockout, Kokietgym hit the canvas due to a hard, accidental head-butt and was granted time to recover. When the action resumed, Rigondeaux immediately connected with two quick punches to end the fight.

With the victory, Rigondeaux made his fifth title defense -- and the last under the Top Rank banner, the promotion which hasn't shown much interest in re-signing him, due to his less-than-entertaining-style.

Rigondeau said before the fight he's interested in unifying the belts against fellow junior featherweight titleholders Leo Santa Cruz and Kiko Martinez. He also said, however, that he didn't think they want any part of him.

Zou Shiming easily outpoints Luis De la Rosa

In the main event, two-time Olympic gold medalist Zou Shiming defeated Luis De la Rosa of Colombia by a wide unanimous decision. The judges' scorecards read 99-91, 99-91 and 97-93 after the 10-round fight. ESPNdeportes.com had Shiming winning 98-92.

It was only Shiming's fifth fight as a professional.

Trained by Freddie Roach, Zou showed vast improvement, as he hit De la Rosa solidly and at will through the duration of the 10 rounds. He managed to open a deep cut on De la Rosa's left eyebrow, further debilitating his opponent.

At the end of the duel, Zou said he was ready for a title shot -- so long as Roach and promoter Bob Arum agree.

Zou, 33, went the distance in his first three fights -- four rounds in his first bout, and then six rounds apiece in his next two fights.

In February, Zou, fighting with a more professional style and settling on his punches, scored his first knockout when he stopped Yachting Kokietgym in the seventh round of his first scheduled eight-rounder.

In other results, super middleweight Gilberto "Zurdo" Ramirez won his third fight in a row by stoppage after dropping Junior Talipeau three times in the first round before the referee stepped in to end the punishment.

Brian "The Hawaiian Punch" Viloria knocked out Mexican José Alfredo "Little Devil" Zúniga in five rounds. Zúniga failed to absorb a relentless body attack from Viloria, and ultimately succumbed before the end of the first round.

Former light heavyweight Olympic gold medalist Egor Mekhontsev sent Mike Mirafuente to the canvas in Round 3, forcing his corner to throw in the towel after the round was over.
