Coco Gauff parts ways with coach on eve of U.S. Open

Two-time major champion and current World No. 3 Coco Gauff parted ways with coach Matt Daly just days before the start of the U.S. Open.

Daly, known as a grip specialist, confirmed his departure to Bounces. He was hired to replace Brad Gilbert after Gauff lost to Emma Navarro in the fourth round of the 2024 U.S. Open.

"Onl y have good things to say about Coco, enjoyed working with her," Daly said of Gauff, who won the 2023 U.S. Open and 2025 French Open.

Gauff, 21, has brought on Gavin MacMillan, a biomechanics specialist who aided World No. 1 Aryna Sabalenka to improve her serve. MacMillan was spotted with Gauff during practice on Wednesday at the Billie Jean King Tennis Center in New York.

A longtime coach, Jean-Christophe Faurel, remains on her team.

The U.S. Open singles main draw play begins Sunday.
