London: Ace Indian shuttler PV Sindhu on Thursday reached the quarterfinals of the All England Open with a straight games win over Korea's Sung Ji Hyun.
Reigning world champion Sindhu beat world No. 12 Sing Ji Hyun 21-19, 21-15 in a match that lasted 49 minutes.
Sung gave a tough fight to Sindhu after stretching her in the first game.
She next faces either Japanese fourth seed Nozomi Okuhara or Denmark's Line Hojmark Kjaersfeldt.
However, 18-year-old Lakshya Sen went down fighting to former world No.1 Viktor Axelsen of Denmark.
Lakshya lost 17-21, 18-21 to second seed Axelsen in a match that lasted 45 minutes.
Later, Ashwini Ponnappa and N Sikki Reddy lost 13-21, 14-21 to Japanese Olympic champions Misaki Matsutomo and Ayaka Takahashi.
Earlier, Saina Nehwal, Kidambi Srikanth and Sai Praneeth were knocked out the tournament on Wednesday.
Sindhu is thus the only Indian challenge left in the competition.
