Shuttler Saina Nehwal has become the first Indian woman to enter the quarter-finals of the World Badminton Championship being played in India.
Nehwal beat 10th seed Petya Nedelcheva of Bulgaria 18-21, 21-18, 21-10 in a match which lasted 57 minutes.
She recently won the Indonesian Open badminton title and became the first Indian to win a Super series tourney.
Nehwal, now ranked eighth in the world, was the first Indian woman to reach the singles quarter-finals at the Olympics.
In a thrilling match in front of a home crowd in the southern Indian city of Hyderabad, Nehwal lost the opening game against Nedelcheva, but bounced back.
The sixth seed Indian will now take on the second seed Chinese Lin Wang in the quarter finals.
The 19-year-old shuttler hails from the northern state of Haryana.
Nehwal is also the first Indian to win the World Junior Badminton Championships.
