COCO GAUFF has ended her partnership with coach Brad Gilbert after 14 months, it was announced today.

While working with Gilbert, Gauff won her first grand slam title at last year’s US Open after coming from a set down to beat Aryna Sabalenka.

However, the 20-year-old was unable to defend her title in New York this year as she crashed out in the fourth round following defeat to Olympic team-mate Emma Navarro.
