Former US Open champion Coco Gauff has split with legendary coach Brad Gilbert following a successful 14-month spell together.

The partnership saw the American star win four titles since the start of July 2023 – including her maiden Grand Slam title in New York last summer – but she was unable to defend her title this year with the 20-year-old knocked out in the fourth round by compatriot Emma Navarro.

A difficult contest saw problems with her serve, hitting 19 double faults and firing 60 unforced errors, with Gauff later admitted her exit was “disappointing”.

Gilbert, who also works as a TV analyst, joined Gauff’s team as a consultant last July before he was promoted to a coaching role in November.

The 63-year-old helped Gauff to a career-high world No 2 in June, but he has now wished her well for the future and said he was looking forward to his next challenge as a coach.

“Thanks to Coco Gauff and the entire team for an absolutely amazing summer run in 2023 and for 14 months of incredible team effort,” Gilbert wrote in a social media message, posted on X.

“Coco, at just 20 years young, your future is incredibly bright, and I wish you nothing but continued success ahead. I’m excited for the next chapter in my coaching career.”

Gauff responded with an X post of her own, adding: “Thank you Brad Gilbert! We had an incredible run and I wish you all the best in the future!”
