India's B Sai Praneeth sailed into the final with a straight-game win but Olympic medallist Saina Nehwal's campaign ended in the semifinal of the $1,20,000 Thailand Grand Prix Gold badminton tournament here today.
In the third game, the Indian however, tightened up her game. He will next face either Indonesia's Panji Ahmad Maulana or ninth seeded Malaysian Iskandar Zulkarnain.
Saina, ranked 11 in the world, defeated Japan's Haruko Suzuki 21-15, 20-22, 21-11 in a women's singles clash that lasted 69 minutes.
It was a mixed day for Indian shuttlers in Bangkok.
21-14, in his opening match that started past midnight, went down 14-21, 18-21 to second seeded Marc Zwiebler of Germany in the second round match, which took place in less than 12 hours of his first-round clash.
Ongbumrungpan defeated Nehwal 21-19, 21-18. After 14-15, however, it was Praneeth all the way as he won seven consecutive points to wrap up the game and the match. Thongnuam made Praneeth work hard for his points, but the Indian had the last laugh.
A little while later, second seed Saina also looked in good nick against Thai fourth seed Busanan Ongbamrungphan. However, Saina came back strongly to win the next two points, before levelling the game at 5-5. Though Saina managed to win the first three points after the break, a brilliant drop shot from the 21-year-old Thai saw her claim the first of four straight points.
