NEW DELHI, March 31: Defending champion Saina Nehwal and two-time World Championship bronze medallist PV Sindhu advanced to the quarterfinals but it turned out to be a dismal day for star shuttlers Lin Dan and Lee Chong Wei, who crashed out of the India Open Super Series here today.
Sindhu was a little circumspect during the match and committed a few unforced errors before surpassing Thailand�s Busanan Ongbumrungphan 17-21, 21-19, 21-16 in a women�s singles match that lasted an hour and 16 minutes here.
She will next take on Korea�s Bae Yeon Ju, who beat Japan�s Yui Hashimoto 21-16, 21-10 in another match.
Later in the day, Saina saw off Nitchaon Jindapol of Thailand 21-19, 21-14 to set up a clash with Korean fifth seed Sung Ji Hyun.
However, the highlight of the day was the stunning loss of world�s top players Lee Chong Wei and Lin Dan, considered to be the biggest contenders for the Rio Games gold medal.
While Korea�s Son Wan Ho stunned the six-time All England champion Lin Dan of China, seeded fourth, 21-13, 22-20, former World No. 1 Lee, top seed, suffered a 19-21, 19-21 loss to Hong Kong�s Wei Nan, ranked World No. 14. Two more top 10 players bite the dust in men�s singles at the Siri Fort Sports Complex here.
While Xue Song saw off Denmark Jan O Jorgensen, seeded 3rd, 21-18, 15-21, 21-14 to emerge as the only surviving Chinese in men�s singles. Germany�s Marc Zwiebler stunned Chinese seventh seed Tian Houwei, who had reached the finals of the All England Championship, 18-21, 21-19, 23-21 in a thrilling contest in the men�s singles. � PTI
