India's star shuttler P.V. Sindhu overcame reigning world champion Nozomi Okuhara of Japan on Friday to enter the semi-finals of the All England Open BWF World Tour Super 1000 here.

The Rio Olympic Games silver medallist edged past seventh seed Okuhara 20-22, 21-18, 21-18 in an hour and 24 minutes in a last-eight women's singles clash here.

In the second game, Sindhu had a three-point advantage at 16-13 but the Japanese hit back and took the lead at 18-16. However, Sindhu displayed superb skills to win the game 21-18 and take the match to the third game.

In the third and decisive game, the Indian looked tired and trailed 12-16 but fought back to equalise with four straight points before sealing the game 21-18.

"It was a good match and she also played really well. It was anybody's game until the last point. I am happy that I pulled off this match. Also I was trailing like 12-16 and then I came back, so I am happy I won it. I just gave my best There were errors in my part as well. I had to control the those errors," Sindhu said after the win.

On her rivalry with Okuhara, she said: "There are good matches every time we play. Prior to the match, we both have won five match each. It not easy to get points from her. She tried to play long rallies like it happened during the World Championship final (in 2017)."
