Her Auckland tournament over, Germany's Sabine Lisicki now faces a nervous wait to see if she will be fit for the Australian Open.
Lisicki will meet doctors today to find out if an abdominal injury will rule her out of the Melbourne tournament, beginning in nine days' time.
The 22-year-old was forced to retire from yesterday's ASB Classic quarter-final against compatriot Angelique Kerber after suffering an abdominal strain, pulling out late in the second set after a medical time-out and receiving treatment during two change of ends.
The tournament top seed was scratched from her doubles match the previous night with cramping after having battled through a tough three-setter against compatriot Mona Barthel in the singles draw and her run of bad luck continued yesterday.
Lisicki said she felt a twinge in her abdominals in the warm-up and the injury got worse throughout the first set.
