French Open champion Svetlana Kuznetsova has become the fifth player currently in the world's top-10 to commit to the Sydney International.
The event, which takes place from January 10-16, is the ideal warm-up for the Australian Open, which gets underway in Melbourne the following week.
"I have had some really great results there in the past and I am looking forward to having a great tournament in Sydney before the Australian Open," said the Russian.
The 24-year-old joins Serena Williams, Elena Dementieva, Caroline Wozniacki and Victoria Azarenka in the main draw for the event.
