Naomi Osaka on Coco Gauff:”She is warm and so respectful.” She adds “I pray she wins in China” See details

Fourth seed Coco Gauff came from a set and a break down to beat Paula Badosa to reach her first China Open final.

The 20-year-old American dug deep to come through 4-6 6-4 6-2.

Spaniard Badosa, ranked 19th in the world but a former world number two, had looked in a good position when she served at 4-3 up in the second set.

But Gauff broke and rattled off the next four games to set up a decider, eventually wrapping up victory in two hours and 21 minutes.

She will face either unseeded Czech player Karolina Muchova or home favourite and fifth seed Qinwen Zheng in the final.

Badosa, who was as low as 140th in the world rankings in May, came into the semi-final meeting on a good run of form in Beijing which included victory over second seed and US Open finalist Jessica Pegula in the last 16.

And she took advantage of Gauff’s inconsistencies, particularly on her serve which produced 11 double faults, to win the opening set and break in the first game of the second.

Gauff is working with new coach Matt Daly after ending her partnership with Brad Gilbert last month following her fourth-round exit at the US Open, where she was defending her title.

She saved four break points to avoid going 4-1 down in the second set and from then the momentum was with the American, who regained her composure as Badosa dropped her first set of the week.

Gauff broke three times in the decider to seal the win as she bids to add to her only title of the year so far from Auckland in January.

“I tried to stay focused, it was tough but mentally I just tried to reset,” she said.
