Her most elevated WTA singles positioning is No. 4, which she came to on 13 May 2019. Bertens won 3-6, 6-3, 6-4 of every two hours and nine minutes in a see-saw match including 12 breaks of serve. Bertens was a late substitution for world No.3 Naomi Osaka, who prior in the day pulled back from the cooperative competition because of a shoulder injury. She seemed apprehensive under the brilliant lights dropping her initial three assistance games and Barty, who has bolted up the year-end number one positioning, jumped to flee with the principal set.

Late section Kiki Bertens paralyzed world number one Ashleigh Barty with a rebound three-set triumph to shake-up the season-finishing WTA Finals in Shenzhen Tuesday. The world No.10 looked in a tough situation at a set and separate, however switched things around with heartless returning and forceful play at the net to overpower a flattened Barty, who could have fixed a spot in the semi-finals with triumph.

Bertens won 3-6, 6-3, 6-4 of every two hours and nine minutes in a see-saw match including 12 breaks of serve. At the outset I didn’t play well yet I think I showed signs of improvement and I attempted to play forceful and go to the net, Bertens said after. Bertens was a late trade for world No.3 Naomi Osaka, who prior in the day pulled back from the cooperative competition because of shoulder damage.

She seemed apprehensive under the brilliant lights dropping her initial three assistance games and Barty, who has bolted up the year-end number one positioning, jumped to flee with the main set. Barty then persevered through her own assistance misfortunes against an inexorably forceful Bertens, who exhibited delicate touch at the net. A drooping Barty had her serve broken multiple times during that time and third sets as Bertens raged to her first triumph over the Australian.

Bertens proceeded with her solid form in the wake of making the finals in Zhuhai a week ago and the semi-finals of the China Open earlier in the month, when she lost a three-set spine chiller to Barty. Bertens, who made the semi-finals a year ago needs to win both her matches to qualify from Red Group. Belinda Bencic needs to win the later match against Petra Kvitova to remain in the competition.
