Jamuna Boro (54kg) got India's campaign in the World Women's Boxing Championships off to a flying start, advancing to the pre-quarter-finals with a facile victory, in Ulan-Ude, Russia, on Friday.
She recovered from a slow start to defeat Mongolia's Michidmaa Erdenedalai 5-0.
The 22-year-old, employed with Assam Rifles, has a tough bout next up, against Algeria's fifth-seeded Ouidad Sfouh.
Sfouh won gold at the 2017 World Championships and was given a first-round bye in this tournament.
Boro, a debutant at the event, took her time to warm-up but once she got going, the Assamese pugilist dominated Erdenedalai with her combination punches.
Her jabs connected particularly well and she did well to stay clam in the face of her sprightly opponent’s grunting. She was unstoppable in the final three minutes of the bout and thoroughly out-punched Erdenedalai.
On Saturday, former National champion Neeraj (57kg) and Saweety Boora (75kg), a former silver medallist at the event, will be in action.
While Neeraj will face China's Qiao Jieru, Saweety will take on Mongolia's Myagmarjargal Munkhbat in the opening round.
