Chinese ace pair Zheng Jie and Yan Zi are set to play Black Cara and Stubbs Rennae Saturday at the WTA Championships in Madrid, Spain.

It will be Zheng and Yan's second battle with the Zimbabwean-Aussie duo this year. The Chinese pair tamed the same rivals 6-2 7-6 (7-3) in the semifinal of the Wimbledon Open early this year before claiming its title.

In another knockout match, American Raymond Lisa will join Aussie Stosur Samantha to compete against Czech-Italian couple Peschke Kveta/Schiavone Francesca for the other berth in the final set for Sunday.

Zheng and Yan have proven to be top women's doubles players since sweeping Grand Slam titles at both the Australia Open and Wimbledon Open this year
