Sindhu will next face top seed and World No. 1 Tai Tzu Ying, hoping to emulate Saina Nehwal and Prakash Padukone, who had clinched this title in 2010 and 1982.
Sindhu marked her spot in the quarter-finals by coming strong over Aya Ohori of Japan and defeating the Asian junior champion 21-14, 21-17. With the 21-18, 21-18 win, the Taiwanese player completed a redux of last year's final - the triumph in Hong Kong which kicked off her year-long reign as world No. 1during which she has collected five Superseries titles. She has already won in India and South Korea.
In the opening game, Sindhu took a 6-2 lead and continued her march ahead. Her silver medal win in the women's singles event of the 2016 Summer Olympics made her the first Indian shuttler to reach the final of an Olympics badminton event and the youngest Indian to make a podium finish in an individual event at the Olympics. Afterwards, even though Tai kept bagging points, Sindhu didn't allow her to run away, keeping herself in the game.

The Thai constructed another post with an angled shot to draw Sindhu near the court and then produced a victor on her backhand. She went on to gain a lead of 11-8 by the break.
In the second game, Sindhu was left to deal with some indecision due to the sidewise drift which gave early advantage to Tai Tzu but the Indian levelled the score at 4-4 with a superb return at her rival's forehand.
Sindhu had to put an extra effort and be patient in the second game as it was a more closely fought contest.
The duo moved to 7-7 before Tai Tzu hit wide and lost a referral too.
