World number one Ashleigh Barty announced Tuesday she will not defend her French Open crown, citing COVID fear that also prompted her and several other top players to withdraw from the US Open. 

The Australian, who claimed her maiden Grand Slam at Roland Garros in 2019, said it was a “difficult” decision but the health of her family and team came first. “Last year’s French Open was the most special tournament of my career so this is not a decision I have made lightly,” she said on social media. “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.”

Barty is based in Brisbane while her coach, Craig Tyzzer, is in Melbourne and unable to travel as the city battles a significant second-wave virus outbreak.

She announced in late July that she would sit out the US Open, currently underway in New York, with defending men’s champion Rafael Nadal and world number two Simona Halep among those who also opted out. At the time, Barty was still monitoring the situation with the French Open, which is due to start on Sept. 27, but said Tuesday her withdrawal was the latest development in “a challenging year for everyone.”
