Laura Robson's hopes of playing at next week's Australian Open suffered a setback when she quit the Hobart International with a left-wrist injury.
The British number one
pulled out of last week's ASB Classic
because of a problem to the same wrist.
The 19-year-old led her first-round match against Belgium's Yanina Wickmayer 6-4 0-2 when she quit.
It was her first competitive outing since teaming up with
American coach Nick Saviano
Melbourne-born left-hander Robson, who
reached the last 16 at Wimbledon
in 2013, has had wrist problems before.
An injury to her right wrist
forced the world number 46 to miss the Rogers Cup last August.
The Australian Open begins on 13 January in Melbourne.
