The 21 & Under Club in '21: Coco Gauff

Will turn 22 on

• 3/13/2026

What she’s done since last summer

• Reached the quarterfinals of the Dubai Duty Free Tennis Championships
• Won her second career WTA title in Parma
• Earned a career-high ranking of No. 25
• Reached a third Grand Slam second week at Roland Garros

Key Stat

• Gauff is the highest-ranked teenager

By the time Gauff ages out of the 21 and Under Club, she will likely be its most prolific member. Still only 17 years old, the American has already achieved much in her short time on tour, including three Grand Slam second week appearances—and a win over Naomi Osaka at the 2020 Australian Open.

Proving herself on all surfaces, Gauff reached the semifinals in Rome and scored her second career title and first on clay last month in Parma, and is into the fourth round of Roland Garros.

Earlier in the season, Gauff was hard at work building her consistency with semi- and quarterfinal finishes at the Adelaide International and the Dubai Duty Free Tennis Championships, respectively.

Gauff has also found her voice off the court, speaking out on behalf of social justice issues.

"We believe the Black experience is rich, diverse and full of stories that deserve to be told," she wrote on social media during Black History Month.

Rather than dealing with too much success too soon, Gauff seems to be taking everything at her own admittedly expedited pace and appears ready to enjoy the ride up to even greater heights.
