Simona Halep and Novak Djokovic will have to wait until tomorrow for their French Open quarter-final matches after thunderstorms caused a washout at Roland Garros for the first time since 2016.

The Romanian third seed had been due to play 17-year-old American Amanda Anisimova as she bids to defend her women's singles title, while Madison Keys of America and Australian Ashleigh Barty had been scheduled to compete in their last-eight match.

Organisers acted promptly to move the women's semi-finals – scheduled for tomorrow – to Friday.

Washouts are a rarity at Roland Garros, with today's torrential downpours causing only the third full day without play at the tournament since 2000.

Thunderstorms delayed play for two hours yesterday and with heavy storms continuing across Paris this morning, organisers took an early decision to suspend play for the day.

Novak Djokovic's match with German fifth seed Alex Zverev and Austrian Dominic Thiem's last-eight match with 10th seed Karen Khachanov of Russia, have also been postponed until tomorrow, meaning they will not get a rest day ahead of potential semi-final contests.

Tomorrow, play will start at noon.

Organisers said spectators with tickets for today (June 5) will have free access tomorrow, but refunds will be offered for those unable to attend.
