Olympic bronze medallist Saina Nehwal became the first Indian to reach the finals of the World Badminton Championships. In the semi-final of the women's singles in Jakarta on Saturday, the World No.2 Indian notched up a 21-17, 21-17 win over Indonesia's Lindaweni Fanetri. Saina is now assured of at least a silver medal. In a repeat to this year's All England Championship final, second seed Saina will fight it out with defending champion and World No. 1 Carolina Marin of Spain in the summit clash tomorrow. In the first semi-final earlier today, Marin had defeated South Korean eighth seed Sung Ji-hyun in three games 21-17, 15-21, 21-16. For India, Saina's medal would be India's fifth medal at the World Championships. P V Sindhu clinched the bronze twice in 2013 and 2014 and Jwala Gutta and Ashwini Ponnappa notched up a bronze in women's doubles at the 2011 edition. Legendary shuttler Prakash Padukone was the first Indian to win a bronze at the 1983 edition.
