Barty passes French Open fitness test

Ashleigh Barty has confirmed her French Open participation in a welcome boost to Australia's flagging stocks at Roland Garros.

Barty allayed fears that she'd join Nick Kyrgios in pulling out of the clay-court major after an hour-long practice session with Fed Cup captain Alicia Molik on Sunday.

Australia's top-ranked player was forced to quit her semi-final in Strasbourg on Friday with a back injury.

But the Open's 17th seed says she'll be ready to meet Russian Natalia Vikhlyantseva in the first round on Tuesday night.

"I had yesterday off and tried to rest and get as much treatment as we could and I was happy to get through that hit today. It was a pretty light one just to test it out," Barty said.

"I'm kind of lucky that the schedule fell in my favour, in a way, and I'll do everything I can to make sure I'm good to go on Tuesday."

Barty said the injury, which hinders "a little bit of everything" in her game, came out of the blue and initially left her deeply upset.

"Never (experienced it before). It was random spasms that came on in my quarter-final match in Strasbourg," she said.

"I was able to get through that and then pulled up pretty lame the next morning."

The 22-year-old is slated to strike Serena Williams in the second round in Paris, where the 23-time grand slam champion is making her grand slam return following the birth last September of her first child.

"I didn't know that was the draw until everybody talks about it and lets you know. You can't hide from that," Barty said of the potential blockbuster.

"But, for me, I've got to focus on getting my body right first and foremost and then, secondly, trying to get my first-round win."
