Fuzhou: P V Sindhu clinched her maiden Super Series Premier title after edging out Sun Yu of China in the finals of the $700,000 China Open badminton here on Sunday.

Sindhu, who became the toast of the country after becoming the first Indian women to win an Olympics silver medal at the Rio Games, lifted the prestigious title after beating Sun 21-11, 17-21, 21-11 in the summit clash that lasted an hour and nine minutes.

Ecstatic after the victory, Sindhu said she was left speechless with emotion. The 21-year-old said: "It has been a dream for a long time to win a Super Series. After the Olympics, everyone was asking me what next? It was important for me to get a Super Series title. Life changed a lot after the Olympics. People thought I will take a long time to get back. But I worked hard," Sindhu said.

"This is my first Super Series title and I am very happy, I have no words to express my feelings," she added.

World No. 11 Sindhu had come into the match with a 2-3 head-to-head record, but then statistics didn't matter when she took the court at the Haixia Olympic Sports Center.

Sindhu dished out a dominating game as she zoomed to a healthy 11-5 lead early on. The Indian looked sharp and athletic as she engaged in a fast-paced game to bamboozle her opponent.

Eventually, it was a cross-court return which earned Sindhu a massive 12 points lead at 20-8. A couple of smashes on Sindhu's forehand and backhand and a drop going to the net helped Sun save three points. But Sindhu sealed the opening encounter after dominating a parallel game and finishing it with a return that hit Sun's face.

In the second game, Sindhu had a slender 6-3 lead, which she extended to 11-7 and 14-10. But Sun soon broke the rhythm to catch up with the Indian at 14-14. A sharp smash and a superb return on Sindhu's backhand helped Sun grab a 18-16 lead which became 19-16 after the Indian lost a video referral. At 20-16, Sun hit the nets but she roared back into contest.

Back to her winning side of the court, Sindhu once again started with new exuberance. Service changed hands rapidly as they moved in tandem till 6-6. But Sindhu moved ahead with a couple of power-packed returns. The Chinese also faltered with a lift and also hit wide as Sindhu reached 10-6. A few errors helped Sun make it 8-10 before Sindhu entered the interval with a 11-8 advantage.

Sindhu continued to extend her lead and was soon 19-11 up. Sindhu then grabbed the match point when Sun let go of the shuttle as it kissed the back line and then the Indian pushed the shuttle at the back, leaving the Chinese stranded before letting out a joyous scream.

Saina Nehwal had clinched the China Open in 2014. Sindhu had reached her maiden Super Series final at the Denmark Open last year, but the title eluded her then.

Talking about the final, Sindhu said: "It is a great day for me. I just thought I can give my best because I practised hard. I was quite confident. From the first round it was tough.

"On Sunday, the first game was very easy. She is also tall like me and we both are attacking players. I lost the second game. In the third I started well and from 11-7, I maintained the lead."

Happy to emulate Saina. she said: "I did what Saina did in 2014 and I am very happy."
