United Cup: World No. 4 Coco Gauff will make her United Cup debut for Team USA alongside world No.7 and US Open finalist Taylor Fritz at the mixed team event, scheduled from December 27 to January 5.

A total of 18 countries, featuring up to three men and up to three women, will compete across Perth and Sydney. Each city will host nine teams each -- three groups of three countries competing in a round-robin format.

The American duo will join Greece’s Stefanos Tsitsipas and Maria Sakkari, China’s Zheng Qinwen and Norway’s Casper Ruud, who have all committed to the third edition of the tournament in September.
