Top India shuttlers PV Sindhu and Kidambi Srikanth progressed to the semi-finals of the Korea Open Super 500 badminton tournament with contrasting wins here on Friday.

Sindhu, the third seed, notched up her 17th win over familiar foe Thailand’s Busanan Ongbamrungphan 21-10, 21-16 in the women’s singles quarter finals, their head-to-head record now being 17-1. Sindhu will next face second-seeded Korean An Seyoung, an opponent who has beaten her twice last year.

In a battle between two former world No.1s, it was World Championships silver medallist Srikanth who rode on his power and precision to outwit local hope Son Wan Ho 21-12, 18-21, 21-12 in a men’s singles quarter final match that lasted just over an hour.

Srikanth had a 4-7 record against the Korean, having lost to him on last three occasions. However, the Indian played better badminton on Friday to come up trumps against an opponent who is coming back to international badminton after a two-year hiatus.

The Indian, seeded fifth, will next face third seed Jonatan Christie of Indonesia, who had claimed the Swiss Open last month. Satwiksairaj Rankireddy and Chirag Shetty failed to make it to the semi-final after going down 20-22, 21-18, 20-22 to Korean pairing of Kang Minhyuk and Seo Seungjae.

In women’s singles, Sindhu had no issues in disposing off Busanan, whom she had beaten at Swiss Open final last month. The Thai lead 5-2 in the opening game but after that it was a Sindhu show as she kept the match under her tight grip.
