The 24 year-old, not known for his punching power, knocked out pre-fight favourite Takashi Uchiyama in the second round to take his belt and in the process inflict a first defeat on the Japanese veteran.
In the co-feature double, WBA Super Flyweight title holder Kohei Kono out-scored Inthanon Sithchamuang convincingly to retain his belt, whilst Ryoichi Taguchi halted Juan Jose Landaeta in the eleventh round to keep a firm grip on his light flyweight version with the World Boxing Association.
Down under in Australia, Jeff Horn claimed a career-best scalp against former IBF welterweight champion Randall Bailey but had to pick himself up off the canvas to do so.
Horn. 28, put Bailey down in the second – even though some may have called it a push, and was forced to take a count himself with the American firing back in the third.
Over the next few rounds, Horn got the better of the majority of the exchanges and eventually wore down Bailey to secure a retirement after seven rounds.
Also on the bill, Solomon Haumono blasted out Manuel Alberto Pucheta in six rounds at heavyweight, whilst Willis Meehan moved to 5-0 in defeating hapless debutant Riki Barclay in the first session.
