Tai produced an impressive performance in her opening match at the Palacio de los Deportes Carolina Marín, having received a bye through the first round.

The Chinese Taipei player earned a 21-10, 21-14 victory over Russian Badminton Federation’s Evgeniya Kosetskaya.

The Olympic silver medallist will continue her pursuit of a maiden world title when she faces Kirsty Gilmour in the third round.

Gilmour achieved an upset win over Singapore’s Yeo Jin Min today, with the Scottish player triumphing 21-15, 8-21, 21-15.

Sindhu began her title defence in formidable fashion, with the Indian star recording a 21-7, 21-9 win over Slovakia’s Martina Repiska.

She will now face Thailand’s Pornpawee Chochuwong, after the ninth seed won 21-13, 21-14 against Belgium’s Lianne Tan.

Sindhu and Tai would meet in a high-profile quarter-final should the pair win their third round contests.

China’s Han Yue benefited from the pre-tournament withdrawal of home favourite and three-time champion Carolina Marin of Spain.

Han will play Michelle Li in the third round, after the Canadian won 21-19, 21-18 against Denmark’s Julie Dawall Jakobsen.

European Games champion Mia Blichfeldt recovered from match point down to win 17-21, 21-13, 22-20 against Turkey’s Nesilhan Yigit.

The Danish player now faces China’s He Bingjiao, who beat France’s Marie Batomene 21-12, 21-15.

Chinese Taipei’s Chou Tien-chen was the main casualty in the men’s singles draw today, with the fourth seed losing 14-21, 21-15, 21-15 to China’s Lu Guangzu.

Lu will meet India’s Srikanth Kidambi in the third round, after the 12th seed came from behind to win 15-21, 21-18, 21-17 against China’s Youth Olympic Games gold medallist Li Shifeng.

Kidambi is now the only seed remaining in the top half of the men’s draw.

Nine of the top 16 seeds are already out of the men’s singles event, due to early defeats or withdrawals through injury.

Guatemala’s Kevin Cordón will be among those attempting to take advantage, with the surprise Tokyo 2020 semi-finalist having reached the third round.

The 35-year-old secured a 21-14, 21-19 win over Poland’s Michał Rogalski, who had received a first round bye due to the withdrawal of two-time defending champion Kento Momota.

Cordon will now play India’s Lakshya Sen, who beat 15th seed Kenta Nishimoto of Japan 22-20, 15-21, 21-18.
