Sumit prevailed 5-0 in the bout against Boltaev, who wasn’t lacking in intent but was definitely nowhere close to the Indian when it came to punching cleanly.

Sumit also copped a warning in the second round for hitting Boltaev on the back of his head repeatedly despite being cautioned by the referee but the docking of one point had no impact on his control over the proceedings as he emerged a unanimous victor.

In a late night bout on Friday, Nishant Dev (71kg) rallied to defeat Mauritian Merven Clair 4-1 to also secure a pre-quarterfinal berth.
