London Olympic bronze medallist shuttler Saina Nehwal produced a fine performance to kick-off her BWF World Championships campaign with a straight game win over Hong Kong’s Cheung Ngan Yi here on Tuesday.

A former World No.1, Saina took 38 minutes to dispatch Ngan Yi 21-19, 21-9 in the opening round. Saina, 32, who has a silver and bronze from the Worlds, moved into the pre-quarterfinals as her second-round opponent, Nozomi Okuhara pulled out of the tournament due to an injury, giving the Indian a bye.
