In a commanding showcase of power and physical dominance, American star Gabriela “Sweet Poison” Fundora successfully defended her undisputed flyweight world championship by stopping Colombia’s Viviana Ruiz Corredor via sixth-round technical knockout. The bout, staged Saturday, March 14, at the Honda Center in Anaheim, California, further cemented the 23-year-old southpaw as the defining force at 112 pounds.

From the opening bell, Fundora made full use of her remarkable height and reach to dictate the tempo. Behind a sharp, piston-like jab and crisp left-hand combinations, the champion kept Ruiz Corredor at long range, repeatedly frustrating the Bogotá native’s attempts to close the distance and work on the inside. While Ruiz Corredor displayed admirable courage and managed to land a few solid shots in the early exchanges, the champion’s steady, punishing offense began to take a visible toll.

The turning point came in the fourth round, when Fundora dropped the challenger with a thunderous right hook followed by a pinpoint uppercut. Though the Colombian rose bravely and continued, the disparity in power and accuracy proved insurmountable. In the sixth stanza, after a sustained barrage left Ruiz Corredor defenseless against the ropes, the referee stepped in to halt the contest at the 2:52 mark.

With the victory, Gabriela Fundora improved her perfect record to 18-0 with 10 knockouts, registering her fourth successful defense of the World Boxing Association (WBA) title and reaffirming her hold on all major belts in the division. Ruiz Corredor, meanwhile, saw her winning streak snapped but emerged with her reputation for toughness intact against a fighter widely regarded as one of the sport’s elite pound-for-pound performers.
