Two-time Olympic medallist PV Sindhu hardly broke a sweat but HS Prannoy had to toil hard as the two Indian shuttlers progressed to the women’s and men’s singles quarter finals of the Syed Modi International Super 300 tournament here on Thursday.

Top seed Sindhu took just 33 minutes to get the better of American Lauren Lam 21-16, 21-13 in her second-round match, while fifth seed Prannoy staved off a stiff challenge from compatriot Priyanshu Rajawat before prevailing 21-11, 16-21, 21-18 here.

Sindhu, a former world champion, will take on sixth-seeded Thai shuttler Supanida Katethong in the last-eight stage in a repeat of the India Open Super 500 semi-finals.

The 26-year-old from Hyderabad will look to set the record straight against the left-handed Thai, who had beaten the Indian last week. Prannoy will clash with France’s Arnaud Merkle, who ended India’s Kartikey Gulshan Kumar’s campaign with a 21-8, 21-12 win in another second-round match.

In other results, Aakarshi Kashyap and Malvika Bansod will clash in the quarters after notching up straight game wins over Sai Uttejitha Rao Chukka and Prerana Neeluri, respectively. While Aakarshi beat Sai 21-9, 21-6, Malvika defeated Prerana 21-10, 21-8.

In another women’s singles second round match, India’s Samiya Imad Farooqui beat compatriot Kanika Kanwal 21-6, 21-15 and will face Anupama Upadhyaya who defeated Smit Toshniwal 21-12, 21-19.

In men’s singles, Mithun Manjunath fought for an hour and 20 minutes before prevailing 16-21, 21-16, 23-21 over Malaysia’s Soong Joo Ven but it was curtains for Chirag Sen, Kaushal Dharmamer and Raghu Mariswamy.

While Russia’s Sergey Sirant quelled Chirag’s challenge 18-21, 22-20, 21-12, Kushal lost 16-21, 13-21 to Cheam June Wei of Malaysia and Raghu went down 9-21, 9-21 to Lucas Claerbout of France.
