Unheralded Sonia Chahal stormed into the finals of Women's World Boxing Championships by outclassing her North Korean opponent Jo Son Hwa, but Simranjit Kaur had to settle for a bronze after losing the semi-final bout here yesterday.

Sonia, 21, who began competing at the senior level only since 2016, registered a unanimous 5-0 win over her more fancied North Korean opponent, a silver medallist in the Jakrata Asian Games, in the 57kg semi-finals to reach the final in her debut World Championships. The rookie boxer joins Mary Kom (48kg) in today's finals. Simranjit, 23, lost to Chinese Dan Dou, a silver medallist in the Asian Championships last year, on a split 4-1 decision in the 64kg semis.
