British number one Johanna Konta suffered a shock defeat by world number 109 Hsieh Su-wei in the first round of the French Open according to reports from the BBC.
Seventh seed Konta dominated the first set but eventually went down 1-6 7-6 (7-2) 6-4 to Taiwanese Hsieh.
Konta, 26, has yet to win a match in the main draw at Roland Garros after three successive first-round losses.
She will now head back to the UK and hope for more success in the grass-court season.
Konta, who is ranked eighth in the world, has also lost twice in qualifying in her five visits to Roland Garros.
Her day was summed up by the final game, in which she missed four chances to break back and stay in the match, one through some Hsieh brilliance and another thanks to the cruellest of net cords.
The Taiwanese player clinched a remarkable win when Konta’s return found the net after two hours and 15 minutes.
Konta’s exit means there are no British women left in the singles draw at Roland Garros, while Andy Murray and Kyle Edmund play in the men’s draw later on Tuesday.
