India’s Nishant Dev outpunched his Mongolian opponent in just over two minutes to progress to the 71kg pre-quarterfinals before Sachin Siwach registered a convincing win in the 57kg weight category of the second Boxing World Olympic Qualifiers here on Tuesday.

Dev began with a flurry of punches against Mongolia’s Otgonbaatar Byamba-Erdeneto force a standing count in the very first minute. A combination of a jab and cross hook led to another standing count and the Referee Stopped the Contest (RSC) with 58 seconds still left to play in Round 1.
