Indian shuttler B Sai Praneeth sailed into the final of Thailand Grand Prix Gold badminton tournament on Saturday with a straight-game win but Olympic medallist Saina Nehwal's campaign ended in the semifinal.
The third seeded Praneeth comfortably beat Pannawit Thongnuam of Thailand 21-11 21-15 in their men's singles semifinal 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, who defeated Joo Ven Soong of Malaysia 21-9 21-18 in his 34-minute semifinal clash.
In Saturday's match, Praneeth started strongly and went into the first break with a four-point lead, paving the way for an easy win in the first game. The Thai tried to stage a fightback in the second game but Praneeth was equal to the task, quickly reducing a three-point deficit. Thongnuam made Praneeth work hard for his points, but the Indian had the last laugh.
