In Badminton, defending champion Saina Nehwal will clash with Olympic champion Li Xuerui of China in the semi-final of the India Open Super Series tournament today. The high-intensity match between the two long-standing rivals will be played at Siri Fort Sports Complex in New Delhi this evening. Having lost to Xuerui 10 times in 12 meetings, Saina will start the match as an underdog. A victory today is bound to be a huge psychological boost for Saina ahead of upcoming Rio Olympics in August.Second-seed Saina stormed into the semi-finals Friday beating 5th seed Sung Ji Hyun of Korea 19-21, 21-14, 21-19. However, ace shuttler P.V.Sindhu failed to make it to the semis as Korea's Bae Yeon Ju defeated Sindhu 21-15, 15-21, 15-21 in another women's singles quarter final last evening.
