Sindhu rattled the Thai by mixing clever net-play with big strokes as she led 13-4 in the first game before securing the 21-13 win.
In the second game, Ratchanok tried to push Sindhu with some clever placements but Sindhu kept firing smashes to quell the challenge from the Thai. The home favourite prevailed 21-15 in the second game.
Following the win at the Siri Fort Sports Complex, the three-time World Championship medallist Sindhu improved her head-to-head record against 22-year-old Ratchanok to 3-4.

The Danish pair looked the better combination in the first game but the Indians did well to fight back in the second game. Pranaav lost his serve at 18-all to give the advantage to Mathias-Christinna, who then made the most of the gift to seal the contest in their favour.
Mathias, especially was brilliant, picking out gaps with ease as Pranaav and Sikki made some tactical errors. Mathias' pace and power made it easy for Christinna, who was playing closer to the net.
