- Australian world No 1 has not competed since US Open
- Withdrawal throws rest of the season into further doubt
Ash Barty has withdrawn from next week’s Indian Wells Masters event, casting further doubt over whether Australia’s world No 1 will play any more tennis this season.
Barty, who has not competed since her shock US Open third-round defeat by Shelby Rogers at the start of this month, was due to compete for the third time at the rescheduled event, one of the biggest on the WTA Tour, which begins next Monday.
