Rio de Janeiro: India’s Avtar Singh lost to Popole Misenga of the Refugee Olympic Team in judo’s 90kg Elimination Round of 32 on Wednesday.

Avtar, from Punjab, lost by a single point at the Carioca Arena 2 on Judo Mat 2 following the end of five minutes of regular time.

The 24-year-old suffered two penalty points that made it difficult for him. Misenga, who hails from the Democratic Republic of Congo, effected a shoulder throw on him to seal the victory.

Former Asian Games gold medallist Vikas Krishan (75kg), however, gave a perfect start to India’s boxing campaign in the Olympics as he outwitted American greenhorn Charles Conwell to enter the pre-quarterfinals.

The 24-year-old Vikas defeated the Olympic debutant 3-0 in his opening contest, which came alive only in the final three minutes, to make the last-16.

The 18-year-old Conwell, who walked in to hostile boos from the local crowd, struggled to launch an attack on the Indian in the opening round. Vikas, on the other hand, used his right straights and uppercuts to good effect in the first three minutes.

Vikas dropped his guard quite early in the bout but Conwell’s attempts at capitalising on it did not quite work out as he landed into a well-laid trap by the counter-attacking Indian.

Vikas seemed more assured in the second round and concentrated on breaking down Conwell’s defence by targeting his torso.

Although the judges were divided in awarding the round to the former World Championships bronze-medallist, Vikas had done enough to secure himself the handy lead going into the final round.

After being seemingly clueless and fetching two cautions for bending excessively in the first two rounds, Conwell gathered himself in the final three minutes to land a couple of crisp jabs but the effort came too late in the day.

The final round ended up being tied between the two boxers but Vikas emerged triumphant on the back of his strong showing in the first two rounds.

Vikas said he wanted to land clear punches and impress the judges to seal the bout against Conwell in the first two rounds so as to avoid a repeat of the London Olympics.

He had won against American Errol Spence in the prequarters but the decision was overturned after a protest four years ago.

“When I saw the draw and got a fight against another US boxer, the London thought came to my mind. I did not want a repeat of what happened four years back. But I had my strategies clear — to beat him in the first two rounds,” he said.
