Indian ace shuttler Saina Nehwal crashed out of the ongoing China Open after facing a 21-10, 21-17 defeat at the hands of Thailand's Busanan Ongbamrungphan in the first round match on Wednesday.
Nehwal faced an early exit from the tournament as she lost to the lower-ranked, currently 18th, Busanan in 44 minutes-long encounter.
Earlier, in the BWF World Championships, the world number eight Nehwal was knocked out of the tournament after facing a defeat in the round of 16-match.
Later in the day, BWF World Championships winner PV Sindhu will face China's Li Xue Rui in the first round match.
