Greater Noida (UP), Dec 22 : The 2016 World Championships silver medallist Sonia Lather of Railway Sports Promotion Board (RSPB) and Tamil Nadu's S Kalaivani started their campaigns with dominating victories on the opening day of the 7th Elite Women's National Boxing Championships here. Sonia started the bout aggressively against Mahi Lama of Madhya Pradesh in the 57kg opening round match before securing a comfortable 5-0 win. Kalaivani, last edition's silver medallist, also proved too strong for Milano Mj of Kerala in the 48kg match.

Kalaivani will now square off against Haryana's Gitika in the next round, who beat Meraj Begum of Telangana by referee stopping the contest in round 1 (RSC) win. Rinku (52kg) and Tannu (57kg) were the other boxers from Haryana to register victories and progress into the round of 16.
