Former champion PV Sindhu's wretched run continued as she bowed out of the World Championships, but HS Prannoy and Lakshya Sen produced commanding performances to enter the third round in men's singles, in Copenhagen on August 22.
Sindhu lacked any sting in her attack and went down tamely 14-21 14-21 to old nemesis Nozomi Okuhara of Japan, a 2017 gold medallist and silver winner in 2019.
In men's singles, world No 9 Prannoy produced a masterclass as he tamed Indonesia's Chico Aura Dwi Wardoyo 21-9 21-14 to set up a clash with 2021 champion, Loh Kean Yew of Singapore.
Earlier, Lakshya Sen, a bronze medallist at the 2021 edition, prevailed 21-11 21-12 over the world No. 51 Korean Jeon Hyeok Jin.
