PARIS: Taiwan's Hsieh Su-Wei knocked British seventh seed Johanna Konta out of the French Open, registering her first victory over a top 10 player.
Hsieh, the 31-year-old world number 109, triumphed 1-6, 7-6 (7/2), 6-4 taking the tie on her second match point when Konta fired a forehand return into the net.
Konta has yet to win a match in Paris in three main draw appearances.
"It was not easy as she is a great player. I had to fight for every point otherwise she would hit a winner or open the court," said Hsieh, who goes on to face Taylor Townsend of the United States.
Konta fired 37 winners but also 38 unforced errors.
