Birmingham, March 15:  Star shuttlers P V Sindhu and Kidambi Srikanth prevailed in tough first-round battles but Saina Nehwal exited from the prestigious All England Championship after suffering a straight-game defeat against World's No. 1 and defending champion Tai Tzu-Ying, here today.

World's No 3 Srikanth recovered from a lop-sided opening game to struggle past France's Brice Leverdez, ranked 23, 7-21 21-14 22-20, while Olympic and world championship silver medallist Sindhu staved off a stiff challenge from Thailand's Pornpawee Chochuwong to prevail 20-22 21-17 21-9 in a 56-minute contest. Srikanth will square off against either China's Huang Yuxiang or England's Rajiv Ouseph, while Sindhu faces the winner of the match between USA's Beiwen Zhang and Thailand's Nitchaon Jindapol.

Singapore Open champion B Sai Praneeth squandered an opening game advantage to go down 21-13 15-21 11-21 to fifth seed Korean Son Wan Ho.

Srikanth was no match for Leverdez in the first game as he failed to execute his strokes properly with most going wide and long. After a pep talk with coach Pullela Gopichand, Srikanth came back strongly in the second game. He looked more aggressive and his approach earned him dividends as he forced the match into the decider after winning 21-14. In the third game, Srikanth was comfortably placed at 11-6 but Leverdez made a fantastic recovery to make it 12-12. The duo fought hard and moved neck and neck till 18-18. Leverdez then won a long rally to grab a 19-18 advantage but Srikanth drew parity. The Frenchman held a match point but the Indian once again levelled par and grabbed a match point, before managing to convert it.

Sindhu, on the other hand, blew an 11-4 advantage in the opening game as Pornpawee fought back to catch up with the Indian at 14-14. She went to the 20-18 game point advantage before Sindhu clawed back but in the end, it was the Thai shuttle who pocketed the game. Jolted by the reversal, Sindhu surged to a 14-6 and 15-7 lead in the next two games and didn't lose control despite some spirited fight by Pornpawee. Saina, who had reached the finals in the 2015 edition, couldn't match up to the precision and athleticism of Tai Tzu and went down 14-21 18-21. It was Saina's eighth successive loss to the Taiwanese wizard in five years.

Among others, Ashwini Ponnappa and N Sikki Reddy lost 14-21 13-21 to second-seeded Japanese combo of Misaki Matsutomo and Ayaka Takahashi, while Jakkampudi Meghana and Poorvisha S Ram went down 14-21 11-21 to fifth-seeded Japanese combo of Shiho Tanaka and Koharu Yonemoto 21-14 21-11 in women's doubles.

Men's doubles pair of Manu Attri and B Sumeeth Reddy also suffered a 20-22 12-21 loss against English combo of Marcus Ellis and Chris Langridge to crash out.

After failing to keep pace with Tai Tzu in the opening game, the 27-year-old Indian blew a 16-11 advantage in the second game to bow out of the USD 1,000,000 world Super 1000 tournament. Saina, who had lost to Tai Tzu in the finals of the Indonesia Masters early this year, showed a lot of grit to keep herself in the rallies but the Taiwanese was simply phenomenal and displayed her mastery of strokes in the 38-minute clash to once again outwit the Indian.

Saina took some time to get in the groove as her first serve sailed over to the back of the court. Tai Tzu didn't waste time and jumped to a 3-1 lead before moving to a 6-2 advantage when the Indian failed to connect a low backhand return. Tai Tzu committed a couple of unforced errors but Saina also made a judgement error on the sidelines and also couldn't reach for a return at the forecourt as the Taiwanese lead 9-4. The Indian, however, grabbed three consecutive points after Tai Tzu erred with a cross-court flick and netted the smash. Saina managed to level 10-10 with a precise crosscourt return from the back of the court but Tai Tzu went into the break with a slender one-point lead.

The duo moved together till 14-14 after the breather before Tai Tzu showed her repertoire of shots even as Saina struggled with her control. Once she again went wide on a return on serve, Tai Tzu had six-game points and she grabbed it with another accurate return on the Indian's backhand.

In the second game, Saina showed better control as she opened up a 3-1 lead and soon made it 10-7 with Tai suffering a mid-game slump with unforced errors. Saina then unleashed a brutal smash to enter the break with the three-point advantage. With the Taiwanese sending the shuttle to the net on four occasions on the trot, Saina managed to lead 16-11. But Tai Tzu once again fought back, riding on her accurate stroke play as she made the Indian run across the court with her acute angled returns. Saina also found the net and sent one long as Tai Tzu narrowed the gap to 15-16 before drawing parity at 17-17 with another razor-sharp crosscourt return from the backcourt. A brilliant block on the move and then a tight net play took the Taiwanese to 20-18 and she shut the door on the Indian after Saina went long again.
