Tshifhiwa Munyai still reigns as the Commonwealth bantamweight champion.
The "Atomic Spider" beat Briton Martin Powers into submission in four rounds to register his second defence last weekend.
The fight was promoted by Frank Maloney at the Goresbrook LC in Dagenham, London.
Munyai won the title in June last year after stopping Powers in nine rounds.
In his first defence at York Hall in London on October 6, the skeletal 21-year-old fighter from Makwarela in Limpopo, whose skills are honed in Gauteng by Rob McLeod, pulverised Lee Haskins over six rounds.
Munyai's prowess forced the hard-to-please British Commission to vote him as the Best International Fighter of 2006.
Munyai was also presented with the inaugural Danny Mancini Award. Munyai's rare achievement away from home saw him win Boxing SA's Special Award last Friday night. He is undefeated in 13 fights, with eight knockouts.
