India's ace shuttler Saina Nehwal will lock horns with China's World Number One Xuerui Li in her must-win second Group-B match of the World Super Series Badminton Finals at Kuala Lumpur, Malaysia on Thursday. Saina, who lost to Japan's Minatsu Mitani, 21-19, 22-24, 19-21 in her opening match on Wednesday, must win the remaining two matches to make it to the semifinals. On the other hand, if Li wins on Thursday, she will advance to the semis. Li won her opener on Wednesday, defeating the other shuttler in the group, Korea's Yeon Ju Bae, 21-9, 21-7. Saina will take on Bae in her final Pool match on Friday.
