Story so far: Wozniacki crashes out

Former world No.1 Caroline Wozniacki has fallen in the opening round at Roland-Garros, bowing to Russian Veronika Kudermetova at Court Philippe-Chatrier.

The 13th-seeded Dane had precautionary strapping on her left calf on Monday but showed no signs of impediment early on, reeling off the first seven games before the 22-year-old from Kazan found her range to advance 0-6, 6-3, 6-3.

At one point, the 68th-ranked Kudermetova took a medical timeout for dirt in her eyes but returned to complete the remarkable turnaround against the 2018 Australian Open champion.

Earlier, sixth seed Petra Kvitova was ruled out before a ball was struck as she withdrew with a left forearm injury.

Slovenian lucky loser Kaja Juvan replaced the Czech in the draw to face Sorana Cirstea.

Home hopes were buoyed with 16-year-old Diane Parry defeating Belarusian Vera Lapko 6-2, 6-4 on Court 8. The French wildcard, ranked No.457, became the first player born in 2002 to win a Grand Slam qualifying match at Roland-Garros last year.

This was her first tour-level main draw match.

Australian No.21 seed Alex de Minaur romped to a 6-1, 6-4, 6-4 victory over American Bradley Klahn, however, 15th seed Nikoloz Basilashvili fell 6-4, 6-1, 6-3 to Argentine Juan Ignacio Londero.

Another Aussie, Ashleigh Barty, cruised to a 6-3 6-3 win over American Jessica Pegula.

Pegula's compatriot, 32nd seed Frances Tiafoe, went down to Serb Filip Krajinovic, falling 6-0 in the fifth set.

Last year’s Wimbledon semi-finalist and No.18 seed Julia Goerges was another early seeded casualty. The German had split six prior meetings with two-time Roland-Garros quarter-finalist Kaia Kanepi, of Estonia, but faded to a 7-5, 6-1 defeat.

Also on Monday, women’s No.4 seed Kiki Bertens extended her clay-court win streak to 13 matches with victory over French wild card Pauline Parmentier, while recent Rome finalist and No.26 seed Johanna Konta eased past Antonia Lottner 6-4, 6-4.
