Johanna Konta's struggles on clay continued as she suffered a hugely disappointing defeat to Hsieh Su-wei in the first round of the French Open.

The seventh seed from Eastbourne was looking for her first main-draw win at Roland Garros but this appeared a kind draw and she raced through the first set.

Hsieh, a 31-year-old from Chinese Taipei ranked 109, went into the match with little form to speak of, especially on clay.

But from unpromising beginnings she turned things around on Court Philippe Chatrier to win 1-6 7-6 (7/2) 6-4 and reach the second round here for only the second time.
