Barty not staying at Covid-19 hit Olympic Village on arrival to Tokyo
Barty leads the field which also includes Naomi Osaka, Iga Swiatek and Aryna Sabalenka but without Bianca Andreescu, Victoria Azarenka, Serena Williams and Coco Gauff among others for varying reasons.
Fresh off her Wimbledon win, she has headed to Japan which has been put under a state of emergency with Covid-19 cases on site spiralling in the Olympic Village.
A likely factor in Barty touching base elsewhere and away from other athletes.
“Ash is staying elsewhere,” said Australia’s chef de mission Ian Chesterman.
“We have a number of athletes staying outside the village. We allow that, it’s just what works best for them.
“Something I’ve always been very big on is driving performance takes a whole lot of flexible decisions, flexible options.
“In terms of her performance plan, it’s best served by her being able to control her environment and we respect that.”
