India's lone hope in men's tennis singles Sumit Nagal powered to a 6-4, 6-7(6), 6-4 win over Denis Istomin of Uzbekistan in the first round here at the Ariake Tennis Court on Saturday.
Nagal's win was the first for an Indian men's singles tennis player at the Olympics since Leander Paes' bronze medal-winning run at Atlanta 1996.
