Irina Mazepa grabs cage, knocks out Ann Osman at ONE Championship 32

The odds were stacked against Irena Mazepa (1-0) when she made her pro debut Friday in Malaysia at ONE Championship 32.

But the Russian flyweight scored the upset of the night, knocking out one of ONE Championship's brightest Malaysian stars, Ann Osman (3-2), with a dramatic sequence midway through the first round that began with a cage grab and ended with a thunderous looping left that sent Osman sprawling to the canvas, out cold. The official time of the stoppage came at 3:05
