London 2012 finalists Lin Dan and Lee Chong Wei both suffered second-round defeats at the Badminton World Federation (BWF) India Open as the shock results continued at the Siri Fort Sports Complex in New Delhi.

Olympic champion Lin of China lost 13-21, 20-22 against South Korea’s Son Wan Ho, while the man he beat at London 2012, top seeded Malaysian Lee, fell to a 19-21, 19-21 defeat at the hands of Hong Kong’s Wei Nan in a tournament that is part of the BWF World Superseries.

Former India Open champion Son notched only his second victory over Lin to set up a quarter-final tie against number eight seed Tommy Sugiarto of Indonesia, who beat Thailand’s Tanongsak Saensomboo 24-22, 21-19.

Wei’s straight-games win over Lee has earned him a last-eight encounter with Denmark’s Viktor Axelsen, a 21-18, 18-21, 21-16 victor against Indonesian veteran Sony Dwi Kuncoro.

Second seed Kento Momota of Japan recorded a comfortable 21-16, 21-11 victory over Hong Kong’s Ng Ka Long and next faces Denmark’s Hans-Kristian Vittinghus, who enjoyed a surprisingly easy 21-12, 21-12 win over Chinese Taipei’s Chou Tien Chen.

In the women’s singles, number two seed Saina Nehwal and unseeded PV Sindhu delighted the home crowd with victories against Thailand’s Nichaon Jindapol - 21-19, 21-14 - and Busanan Ongbumrungpan - 17-21, 21-19, 21-16 - respectively.

Men’s doubles defending champions Chai Biao and Hong Wei of China were toppled by young Indonesian pair Kevin Sanjaya Sukamuljo and Gideon Markus Fernaldi in arguably the closest match of the day, losing 20-22, 21-19, 18-21.

Sukamuljo and Fernaldi go on to meet Chinese Taipei’s Chen Hung Ling and Wang Chi-Lin, who eased to a 21-19, 21-12 success against India’s Sumeeth Reddy and Manu Attri.

Women’s doubles sixth seeds Jung Kyung Eun and Shin Seung Chan of South Korea were beaten 21-16, 23-21 by Japan’s Naoko Fukuman and Kurumi Yonao.

Another favoured Japanese pair, Misaki Matsutomo and Ayaka Takahashi, set up a clash with number eight seeds Eefje Muskens and Selena Piek of The Netherlands after staving off a late challenge from Bulgaria’s Gabriela Stoeva and Stefani Stoeva to triumph 21-12, 21-19. 

Muskens and Piek had a similar victory over South Korea’s Go Ah Ra and Yoo Hae Won, prevailing 21-17, 21-19.
