Paris, France , 6 June 2019 | AAP /

The weather gods halted Ash Barty’s French Open charge on Wednesday, leaving Australia’s title hope needing to win three matches in three days to lift the trophy.

Barty was holed up in the locker room for all but 10 minutes as persistent rain wiped out play on Wednesday, resulting in a gruelling new schedule for the remaining contenders.

Barty’s quarterfinal against American powerhouse Madison Keys was pushed back until Thursday (8pm AEST), with the winner to back up on Friday against either defending champion Simona Halep or American teenager Amanda Anisimova for a place in the final.

Britain’s Johanna Konta and 19-year-old Czech Marketa Vondrousova will contest Friday’s other semifinal.

Apart from a brief spell hitting on Court Suzanne Lenglen before ground staff scrambled to cover the courts as the heavens opened in Paris, Barty spent the rest of the day cooling her heels in the players’ lounge.

But the unflappable star took the delay in her stride, taking to Twitter to celebrate her beloved Queensland’s State of Origin rugby league series opening win over NSW.

A doubles finalist two years ago with Casey Dellacqua, Barty is bidding to become Australia’s first French Open singles champion since Margaret Court in 1973.
