Oriental and Pacific Boxing Federation (OPBF) flyweight champion Jay-r Raquinel of Cauayan retained his title over the weekend after knocking out Shun Kosaka Japan in the fourth round of their bout in Wakayama, Japan.

Raquinel managed to land a left hook to Kosaka’s jaw, sending him to the canvas.

This marks his second straight win in Japan after initially earning the belt in March of this year after his fight against Keisuke Nakayama of Japan was stopped in the ninth round./JSG, WDJ
