JOHNRIEL Casimero scored a 10th round technical knockout over Charlie Edwards on Saturday night (Sunday morning, Manila time) to retain his International Boxing Federation (IBF) flyweight title at the O2 Arena in London.
The Filipino ended the upset bid of the British challenger when he landed a vicious left hook that sent Edwards down on his back.
The British managed to beat the count, but Casimero quickly swarmed all over him when the fight resumed, prompting referee Steve Gray to stop the bout at the one minute and 57-second mark of the 10th round.
Casimero, 26, jumped and run around the ring with both hands raised in triumph, having showcased to the world his boxing talent in the undercard of the Gennady Golovkin-Kell Brook world middleweight title showdown.
The Filipino champion improved his record to 23-3, with 15 KOs as he retained the belt he won by knockout over Amnat Ruenroeng of Thailand last May in Beijing, China.
The 23-year-old Edwards lost in his first bid for a world title in only his ninth fight as a pro and fell to an 8-1 record (3 KOs).
