Singapore mixed martial arts fighters scored a hat-trick at One Championship's Pride of Lions card at the Singapore Indoor Stadium on Friday evening.

Benedict Ang, Amir Khan and Angela Lee each notched dominant victories to cheer up fans disappointed with the cancellation of the co-main event involving welterweight champion Ben Askren.

His opponent, Brazilian Luis Santos, refused to make weight for the second time in as many days, leading Askren and One chief executive Victor Cui to accuse him of unprofessionalism and cowardice.

It was left to hometown talents to entertain a raucous crowd of over 8,000.

Strutting into the ring to the iconic "Kung Fu Fighting" tune, 19-year-old Ang showcased Bruce Lee-esque kicks and punches to force a corner stoppage from Indonesian featherweight Yohan Legowo after two rounds.

Fellow featherweight Amir, who entered the evening with a 3-2 record, was next to deliver a telling blow.

Facing Filipino kickboxer Jimmy Yabo, the 21-year-old tried a spinning kick early on but lost his balance. It was his usual ground-and-pound game that had his adversary tapping out late in the first round.

Amir said: "Once I had him in position on the mat, I knew I'd finish him with my fists."

Lee capped a perfect night for the locals with her third straight win by submission.

Amid raucous chants of "Angela, Angela", she locked Australian Natalie Hills in a "twister" neck crank for an opening-round triumph.

Born in Canada and raised in Hawaii, the 19-year-old was in tears after the bout when discussing her recent move to Singapore after turning professional.

She said: "I was very homesick at first but the support I got tonight reminded me just why it's so special to fight for Singapore."
