John Riel Casimero kept hold of his WBO bantamweight championship with a split decision victory this past weekend on Showtime Boxing.
Casimero bested top contender Guillermo Rigondeaux from the Dignity Health Sports Park in Carson, California.
A three-division world champion, Casimero (31-4, 21 KOs) made his second successful title defense at 118-pounds, earning a career-best victory over the longtime 122-pound champion Rigondeaux (20-2, 13 KOs), who moved down to bantamweight in 2020.
“I’m excited to get the win,” said Casimero. “Rigondeaux is a good boxer and two-time Olympic gold medalist. I was worried, because he said he wouldn’t run, but he ran the whole time.”
Those power punches and sustained aggression proved to be enough for Casimero to hold onto his 118-pound title in the eyes of the judges, as scores of 117-111 and 116-112 overruled one judge’s 115-113 card in favor of Rigondeaux. While Rigondeaux disputed the decision, Casimero looked forward to potential unification clashes with WBC champion Nonito Donaire and WBA and IBF titleholder Naoya Inoue.
“My expectations were for a knockout,” said Casimero. “Me and all my fans wanted that. I did my best to knock him out, but he was just running and not fighting.”
The co-main event saw rising contender Gary Antonio Russell (18-0, 12 KOs) and former world champion Emmanuel Rodriguez (19-2, 12 KOs) fight to a no-decision just 16 seconds into the first round of their 118-pound matchup, after an accidental headbutt injured Rodriguez and ended the fight.
In the opening bout, former world champion Rau’shee Warren (19-3, 5 KOs) dominated Damien Vazquez (16-3-1, 12 KOs) on his way to a second-round stoppage in their bantamweight showdown. Warren scored his first knockout victory since 2015, after going the distance in his previous eight fights.
