Having reached Tokyo on Sunday along with the first batch of the contingent, Sindhu, who had been training at the Gacchibowli stadium in Hyderabad with coach Park Park Tae-sang, is the favourite to win the gold medal, to add to the silver she won five years ago. Seeded sixth, Sindhu will open her campaign in Group J on July 25 with the match against Ksenia Polikarpova of Israel.
