1. Who Is Coco Gauff — Her Age and Rising Stardom

Cori Dionne “Coco” Gauff was born on March 13, 2004, in Delray Beach, Florida, U.S.—making her 21 years old as of August 2025.

At just 15, she made a sensational breakthrough by defeating Venus Williams in the main draw of Wimbledon, becoming the youngest qualifier ever to reach the tournament proper. Since then, Gauff has rapidly ascended the sport:

• Achieved a career-high singles ranking of world No. 2 in June 2024.

• Secured two Grand Slam singles titles: the 2023 US Open and the 2025 French Open.

• Claimed the 2024 WTA Finals singles title, becoming the youngest female player to do so since Maria Sharapova in 2004, and set a record for largest single-event prize money in women’s pro tennis ($4.805 million) Wikipedia.

• Won prestigious WTA 1000 titles—including the 2024 China Open and other major tournaments.

Her rise is defined by poise, athleticism, and a maturity beyond her years.

2. Coaching Staff: Shake-ups and New Faces

Recent Shake-Up

Before the start of the 2025 US Open, Gauff made a bold move: parted ways with longtime coach Matt Daly and brought on board biomechanics expert Gavin MacMillan to refine her serve.

Despite earlier reports, J.C. Faurel remains part of her team.

Coco explained that this change was motivated by the need for more serving consistency and technical improvement, especially following struggles on grass and during the North American hard-court swing.

Who Is Gavin MacMillan

MacMillan is a respected biomechanics specialist known for successfully transforming Aryna Sabalenka’s serve—making him a strategic hire to address Gauff’s double-fault issues.
