Bangkok: India's B Sai Praneeth sailed into the final with a straight-game win but Olympic medallist Saina Nehwal's campaign ended in the semi-final of the $120000 Thailand Grand Prix badminton tournament here on Saturday.
The third seeded Praneeth comfortably beat Pannawit Thongnuam of Thailand 21-11, 21-15 in their men's singles semi-final that lasted 36 minutes.
London Olympic bronze medallist Saina, however, had to bite the dust as she lost in straight games to Thailand's Busanan Ongbamrungphan 19-21, 18-21 in 53 minutes.
The world number 11 Saina, who made the women's singles semi-final, was seeded second in the tournament, while her opponent entered the tournament as fourth seed. Singapore Open champion Praneeth, ranked 24 in the world, will take on fourth seeded 19-year-old Indonesian Jonatan Christie in the final today.
