PV Sindhu suffered a shock defeat at the China Open on Thursday.
The newly-crowned world champion lost in three games to Thailand's Pornpawee Chochuwong 21-12, 13-21, 19-21.
There was no joy either for India's men's doubles pair or mixed doubles team, as they also bowed out of the tournament.
Going to plan
It all appeared to be going to plan for Sindhu early on.
The Olympic silver medallist dominated the opening exchanges with an opponent she had never previously lost to.
Chochuwong pulled back an early deficit to just one point at the break, but Sindhu then pulled away again to take the first game 21-12.
Sindhu had made serene progress past former Olympic Champion Li Xueri in the first round, but world number 15 Chochuwong proved an entirely different prospect.
By the second mid-game break, the Thai shuttler had opened up a four-point lead at 11-7 and followed it up to 15-7.
Sindhu did try cutting back the deficit, but it was just too little too late for her - the closest she came was at 13-19. Chochuwong did not allow Sindhu another point and the match was heading into a deciding game.
Into the decider
There was nothing to choose between the pair at the start of the third game, with the shuttlers tied at 6-6.
Then Sindhu moved into the ascendancy, building a 11-7 advantage at the break.
Her Thai opponent though never gave up the fight and was rewarded for her perseverance.
Trailing 15-19, Chochuwong registered four consecutive points to bring the game back on level terms. Two more points and the game was set. After more than 50 minutes on court, Sindhu was eliminated 21-12, 13-21, 19-21.
Her departure in Changzhou follows Saina Nehwal's opening round defeat to another Thai player, Busanan Ongbamrungphan.
India’s woes continue
Earlier on Thursday, the men’s doubles pair of Satwiksairaj Rankireddy and Chirag Shetty crashed out of the tournament after losing 19-21, 8-21 to Japan's Takeshi Kamura and Keigo Sonoda.
While the Indians put up a strong fight against the Japanese pair in the first game, they were no match to Kamura and Sonoda’s artistry in the second. Opening up an early five-point lead, the Japanese shuttlers went on to dismantle the Indian duo in absolute style.
Rankireddy also took to the court in the mixed doubles with Ashwini Ponnappa but the Indians managed to only come out as second-best after playing a three-game thriller against Japan’s Yuki Kaneko and Misaki Matsutomo.
Losing 11-21 21-16 12-21, the Indian pair hardly gave a fight in the first game after going down by the break. A comeback in the second game though was followed utter disappointment in the third.
