Juanito Rubillar of the Philippines retained his OPBF light-flyweight crown with a fifth-round knockout over Japanese challenger Ken Nakajima minutes ago at the Nishinari Ward Gym in Osaka, Japan.
Rubillar’s two-fisted body shots sent Nakajima down twice, and the one-sided attack continued, prompting the referee to stop the fight at the 2:42 mark of the round.
