Zheng Qinwen isn't hiding that she is very happy with her game and results but admits that the Aryna Sabalenka challenge is the thing that motivates her to work harder because she feels that's what she needs to figure out next if she wants to win a Grand Slam.

Coco Gauff may be saving the best for last. In what is shaping up to be potentially her best week of the season, Coco Gauff beat the world No. 1 Aryna Sabalenka in two turbulent sets Friday to set up a championship battle against the Olympic gold medalist Zheng Qinwen this weekend at the WTA Tour Finals.

Main favorites Aryna Sabalenka and Iga Swiatek have been eliminated, both pretty much at the hands of Coco Gauff.
