Ash Barty has succumbed to a nagging thigh injury which had been heavily strapped throughout her Australian Open run, as well as her shock loss at the Adelaide International.
It hasn't been Barty's month, despite managing to hold on to her world No.1 status after Naomi Osaka won the Australian Open over American star Jennifer Brady.

The 23-year-old's run through her home grand slam came to a premature end in the quarter finals against Karolina Muchova, while she was unceremoniously dumped from the Adelaide International first round in straight sets by Danielle Collins.
In the wake of the surprise loss, Barty said she would require some time to fully recover from the thigh complaint, with next month's Miami Open and the Porsche Grand Prix in Stuttgart Barty's next most likely appearences.
"Unfortunately I have withdrawn from the Qatar Total Open with a left leg injury," Barty said.
"I wish the tournament a safe and successful event and hope to play there next year.
"Thank you to the event organisers and the WTA for all the work you are doing, I look forward to competing again in Miami in a few weeks time."
Following the loss to Collins, Barty was circumspect about her preparation for the tournaments in Australia.
"You know that there are no easy matches going into any tournament," Barty said.
"From an expectation of a public point of view, I think that (winning all the time) is their views and that's their opinions and they are 100 per cent able to voice those.
"But I think from a playing perspective, it's about what do we expect from us as players and what do we bring to the court each day. We bring the right professionalism and prepare in the right way.
"And in the end, the result, it just is what it is, it's not always going to go your way.
"You can't win every single tennis match. But you can sure as hell approach it the right way.
"And from my team and from me, we did that this week and we just didn't quite get that result."
Ash Barty mulls over next move after injury
Barty will now take stock before deciding if, where and when she will play again outside of Australia.
The Queenslander was absent from the world tour for almost 12 months before returning to competitive play on February 2 - she has since played 11 matches in 22 days.
"We will sit down like we always do at the end of a match after a tournament and look at what is next," she said.
"I will have that discussion with my team in the next day or so to work out as best we can what we will do moving forward.
"Obviously it's an ever-changing world that we're living in now, things can change quite dramatically quite quickly."
Organisers of April's Porsche Grand Prix are also evidently confident Barty will be in Stuttgart for their star-studded opening to the clay court season.
They announced on Wednesday that Barty would be joined there by second-ranked Simona Halep and newly-crowned Australian Open champion Naomi Osaka.
