Indian boxer N Lalbiakkima,49kg notched up a sensational triumph over Olympic champion Hasanboy Dusmatov to enter the semifinals of the President’s Cup Tournament in Astana, Kazakhstan today.

Lalbikkima, hailing from Manipur, prevailed 4-1 to clinch the biggest win of his career and assure himself of a medal. Dusmatov is also a silver-medallist from last year’s World Championships.

Also advancing to the semifinal was former world youth champion Sachin Siwach,52kg. The Indian youngster claimed a 4-1 win over Thailand’s Yurachai Wuttichai to make the last-four stage.

However, Devanshu Jaiswal bowed out after going down to Uzbekistan’s Melikuziyev Bektemir in his quarterfinal bout.
