News Now:WTA Finals: Coco Gauff beats world No 1 Aryna Sabalenka to set up Qinwen Zheng final in Riyadh

Coco Gauff twice battled back from a break down when taking the opening set on her way to a 7-6 (7-4) 6-3 victory over world No 1 Aryna Sabalenka; Olympic gold medallist Qinwen Zheng awaits in the final on her WTA Finals debut after defeating Wimbledon champion Barbora Krejcikova 6-3 7-5

Coco Gauff put in a sensational display to beat world No 1 Aryna Sabalenka and book a place in the final of the WTA Finals Riyadh, where she will face Qinwen Zheng.

Gauff twice battled back from a break down to take the opening set in a tie-break, before romping through the second to clinch a 7-6 (7-4) 6-3 victory.

Gauff broke Sabalenka on four straight occasions in the second set on her march to the final, allowing for a late wobble when twice dropping her own serve.

“I’m happy with the way I played,” Gauff said after her semi-final win. “I know that coming up against Aryna, she’s always going to be a tough match, she is world No 1 for a reason.

“Zheng is playing great tennis too, but I just need to play confidently, that will help me win. I’m not nervous. Being here is a reward for the season I’ve had.”

The 20-year-old American will take on Zheng in the final, the Olympic champion from the Paris Games this summer cruising past Barbora Krejcikova 6-3 7-5 in the other semi-final.

It caps a remarkable run for the Chinese 22-year-old who is making her maiden appearance at the WTA Finals.
