The women produced three first-time winners, none of whom was, bizarrely, Caroline Wozniacki.
She also hired a coach, Sven Groeneveld, who has worked with some of the top able-bodied players, including current world number 1 Caroline Wozniacki.
The second-ranked Russian's withdrawal ensures that Caroline Wozniacki will finish the year with the No. 1 ranking, despite losing her group-stage match against Russia's Vera Zvonareva.
She won 6-4 6-2 to follow up her second successive win over world No. 1 Caroline Wozniacki and set up a clash with fourth seed Victoria Azarenka.
