Gauff beats Pegula to win all-American Wuhan Open final; Vacherot in shock after 'crazy' Shanghai triumph

Coco Gauff overcame Jessica Pegula 6-4, 7-5 on Sunday to clinch the third WTA IOOO title of her career in an all-American final at the Wuhan Open.

- 

The third-seeded Gauff secured the trophy without dropping a set after a 1hr 42min battle in the central Chinese city.

In the first final between the former doubles partners, Gauff erased multiple deficits in the second set to improve her head-to-head record against Pegula to 3-4.

The 21-year-old in the process became the first player in the Open Era to win her first nine hard-court finals.

The pair had contrasting routes to the final with Gauff breezing dropping a mere 16 games while Pegula battled through three-setters in all eight of her previous matches.

Gauff won the first six points of the match and it set the tone for what was to come, as she leapt to a 3-0 advantage.

Pegula recovered from her slow start and went on the attack in game seven, breaking with a fierce backhand winner that helped her get back on level terms at 4-4.

It looked like the sixth seed had swung the momentum her way but Gauff found a tiny opening two games later and broke to secure the opening set in 47 minutes.
