Sindhu, seeded third, continued her consistent run as she recovered from a mid-game slump to surpass Thailand’s Nitchaon Jindapol 21-15 13-21 21-17 in the opening round which lasted a little over an hour.
It was Sindhu’s fourth win over the Thai player.
Sindhu, who won three major silver medals this season — Commonwealth Games, World Championship and Asian Games — will take on Korea’s Sung Ji Hyun next.
The 23-year-old from Hyderabad has a superior 8-5 head-to-head record against the Korean.
In the men’s singles, Sameer, who clinched the Swiss Open and Hyderabad Open this year, saw off another Thai Suppanyu Avihingsanon 21-17 21-14 to set up a clash with China’s Olympic champion Chen Long.
However, former Singapore Open champion B Sai Praneeth was stunned by Khosit Phetpradab of Thailand in a 62-minute opener.
Praneeth had a 3-0 record against Khosit ahead of the match but it didn’t matter as he went down fighting 21-16 11-21 15-21 to bow out of the tournament.
