Women's world number one Ashleigh Barty has confirmed that she won't be defending her French Open tennis title later this month.

The Australian, who landed her maiden Grand Slam at Roland Garros in 2019, has cited concerns around the coronavirus pandemic as her reason for not travelling to the event.

Barty is also among of host of top players who chose not to play at this month's US Open in New York.

"It has been a difficult decision to make but unfortunately I will not be competing in Europe this year," Barty announced on instagram.

"Last year's French Open was the most special tournament of my career so this is not a decision I have made lightly.

"There are two reasons for my decision. The first is the health risks that still exist with COVID.

"The second is my preparation, which has not been ideal without my coach being able to train with me due to the state border closures in Australia.

"I wish the players and the French Federation all the best for a successful tournament.

"I now look forward to a long pre-season and the summer in Australia. It has been a challenging year for everyone and although I am disappointed on a tennis front, the health and well-being of my family and my team will always be my priority.

"Thank you to my fans for your continued support, I can't wait to play for you again."
