Olympic medallist Sakshi Malik and Asian Games gold medallist Bajrang Punia will spearhead the 30-member Indian contingent at the World Wrestling Championships to be held in Budapest, Hungary from October 20 to 28. The Wrestling Federation of India has selected 10 members each in freestyle, Greco-Roman and women's wrestling categories. The burden of India's medal hunt at the worlds will mostly be on the shoulders of Bajrang (65kg) and Sandeep Tomar (57kg) in the men's freestyle category. In the women's section, Sakshi (62kg), Pooja Dhanda (57kg) and Ritu Phogat (50kg) are expected to be strong medal contenders in their respective weight categories. Ritu is the only Phogat sister to feature in the squad as Asian Games gold medallist Vinesh was ruled out because of an elbow injury during the trials. Four wrestlers -- Bajrang, Kuldeep, Gurpreet and Harpreet -- have been training in Hungary for more than a fortnight while the rest of the squad joined a week back.
