Australian Open champion Angelique Kerber has been dumped out of Roland Garros by unseeded Dutch player Kiki Bertens.
The third-seeded German was beaten 6-2, 3-6, 6-3 by her opponent ranked 58th in the world.
Incidentally, it is the second time in three years that the winner of the Australian Open suffered a first round defeat at Roland Garros, after the same thing happened to Li Na in 2014.
Kerber never really looked at home on the clay courts of Paris and went off for treatment on her injured shoulder when trailing 3-0 in the final set.
The left-hander returned and won her next service game without incident, but couldn’t gain back the break of serve and lost the match a few minutes later.
Kerber arrived in the French capital having lost early in both the Madrid and Rome Masters tournaments, before withdrawing from the tournament in Nuremberg last week.
The 2010 winner at Roland Garros, Francesca Schiavone was also handed an early exit when the Italian veteran suffered a 6-2, 6-4 defeat to local player Kristina Mladenovic, the 24th seed, this time around.
Alize Cornet claimed a 6-1, 6-0 victory over Kirsten Flipkens, and 23rd-seed Jelena Jankovic suffered a 6-3, 3-6, 6-3 defeat to another German, Tatjana Maria.
China’s Wang Qiang advanced to the second round after beating French teenager Tessah Andrianjafitrimo 6-0, 6-0 in just 51 minutes.
The 17-year-old Andrianjafitrimo was playing in her first match in the main draw of a grand slam, having entered the tournament as a wildcard.
Eugenie Bouchard proved far too strong for Laura Siegemund, winning 6-2, 6-2, but Saisai Zheng’s Roland Garros campaign came to an end.
The 22nd-seed Dominika Cibulkova proved just too strong for the Chinese player, winning 6-3, 6-1 in 75 minutes.
Another Chinese player, Shuai Zhang, had no trouble in booking her place in the second round when she beat the unheralded Kazakhstan player Galina Voskoboeva 7-5, 6-2.
Japan’s Misaki Doi’s campaign came to an end when the 21st-seeded Australian Sam Stosur won 6-2, 4-6, 6-3.
