Commonwealth Games champion Lakshya Sen continued his impressive run, defeating Danish Hans-Kristian Solberg Vittinghus in straight games to progress to the men’s singles second round at the BWF World Championships here on Monday. Kidambi Srikanth and HS Prannoy also won their respective first-round matches.

India also registered twin wins in women’s and mixed doubles competition on the opening day which saw B Sai Praneeth bow out after losing in three games to world number 4 Chou Tien Chen of Chinese Taipei. The 20-year-old Sen, who had returned with a bronze on his debut in Spain last year, prevailed 21-12, 21-11 over an erratic Vittinghus in his opening match.

Sen will next face Luís Enrique Penalver of Spain. Praneeth, a 2019 bronze medallist, put up a brave effort before going down 15-21, 21-15, 15-21 to Chen in little over an hour. Srikanth, seeded 12th, had to toil in his 22-20, 21-19 win over Nhat Nguyen of Ireland. Prannoy secured a dominating 21-12, 21-11 win over Luka Wraber of Austria.

Former Commonwealth Games bronze medallists Ashwini Ponnappa and N Sikki Reddy progressed to the women’s doubles second round with a 21-7, 21-9 win over Maldives’ Aminath Nabeeha Abdul Razzaq and Fathimath Nabaaha Abdul Razzaq.

The Indians have a tough task against top seeds Chen Qing Chen and Jia Yi Fan of China in the second round. In mixed doubles, Tanisha Crasto and Ishaan Bhatnagar defeated the German duo of Patrick Scheiel and Franziska Volkmann 21-13, 21-13 in 29 minutes. In another women’s doubles match, India’s Pooja Dandu and Sanjana Santosh beat the Peru pair of Ines Lucia Salazar and Paula Regal 21-6, 10-21, 21-14.
