A quartet of defending champions advanced to the semi-finals at the Asian Boxing Championships in Dubai, as medallists were decided in six more men's divisions.

Uzbekistan's Bobo-Usmon Baturov was among them, as the nation enjoyed another impressive day at the Asian Boxing Confederation event, with all six fighters progressing.

Baturov, the defending welterweight champion at 69 kilograms and under, overwhelmed Asian youth champion Nuradin Rustambek Uulu of Kyrgyzstan and was at least a 30-26 winner in the eyes of all five judges.

World and Asian super-heavyweight champion Bakhodir Jalolov of Uzbekistan has additionally progressed, but via walkover.

Amit Panghal, the returning under-52kg champion who was expecting to fight on home turf before the event was moved from India to the United Arab Emirates in response to the coronavirus crisis, found the going harder in his quarter-final.

Facing Mongolia's Enkhmandakh Kharkuu, the Indian won 3-2 on the judges' scorecards.

There was better luck for Kharkuu's compatriot Erdenebat Tsendbaatar, the under-60kg king, who outclassed Kyrgyzstan's Munarbek Seitbek Uulu and collected a 5-0 win.

Kazakhstani fighter Bek Nurmaganbet was the other defending champion in action today but suffered a shock defeat.

Meysam Gheshlaghi of Iran triumphed 4-1 on the judges' scorecards in the light-heavyweight quarter-final.

Uzbekistan's Dilshodbek Ruzmetov - seeded second in the division and a silver medallist at the 2019 World Championships, where he lost to Nurdauletov in the final - was victorious on the other side of the draw, and could be a beneficiary of the surprise result.

The Asian Championships continue tomorrow.
