India shuttlers PV Sindhu and HS Prannoy advanced to the women’s and men’s singles semi-finals of the Malaysia Masters Super 500 tournament with hard-fought wins here on Friday.

While double Olympic medallist Sindhu, seeded sixth in the tournament, beat lower-ranked Yi Man Zhang of China 21-16, 13-21, 22-20, Prannoy earned a 25-23, 18-21, 21-13 win over Kenta Nishimoto of Japan in the quarter finals.

Sindhu faces seventh seed and world No. 9 Gregoria Mariska Tunjung of Indonesia in the semi-finals on Saturday. Tunjung upset second seed Yi Zhi Wang of China in the quarter finals 21-18, 22-20.

Tunjung has been in fine form recently and Sindhu had lost to her in the Madrid Spain Masters final in straight games in April. The Indian will, however, go into the semi-finals with a 7-1 head-to-head advantage over Tunjung.

World No. 9 Prannoy faces qualifier Christian Adinata, ranked 57, of Indonesia, who beat Kidambi Srikanth 16-21, 21-16, 21-11, in the last-4 on Saturday.

Prannoy has never played against the 21-year-old Adinata, who began playing at the senior level just last year.

For world No. 13 Sindhu, it was a revenge of sorts for her round-of-32 loss to Zhang, ranked 18th, in the All England Open earlier this year.

In the first game, Sindhu found herself on the back foot as she trailed 0-5, but she made a fine recovery and made the score 10-all. After that, Sindhu led all through and clinched the first game 21-16.

In the second game, Zhang learnt her lessons and did not allow Sindhu to come back unlike in the first. From 2-all, it was Zhang who led all through till the end to make the tie 1-1.

The decider was neck-and-neck all through and it could have gone either way.
