Laura Robson's run in the Shenzhen Open ended in the second round, with the Briton losing in straight sets to Romania's Monica Niculescu.
Despite crushing Niculescu's compatriot Edina Gallovits-Hall 6-2 6-1 in the first round, the Olympic mixed doubles silver medallist - who was seeded seventh - lost 6-2 6-3.
The world number 53 will now spend the remainder of the week fine-tuning her preparations for the Australian Open which starts on January 14.
