The men's hockey team broke a 12-year-old Olympics jinx by winning their opening group league encounter against minnows Ireland, while Bhokanal entered the quarterfinals by finishing third in his heat in men's singles sculls rowing competition.
Those were the only bright spots as the Indian contingent faced reversals in the shooting range, tennis court, table tennis and weightlifting arena on Saturday.
On the tennis court, Paes' dream of winning his second Olympics medal -- after a bronze in 1996 Atlanta -- in his record seventh appearance was blown away when he and his doubles partner Rohan Bopanna were knocked out in straight sets in the opening round by the Polish pair of Marcin Matkowski and Lukasz Kubot. The Indians lost 4-6 6-7 (6-8).
Later, star woman player Sania Mirza, the world number one in doubles, too could not lift the Indian contingent's sagging spirits as she and much lower ranked partner Prarthana Thombare went down to the Chinese pair of Shuai Zhang and Shuai Peng.
