Why Coco Gauff could easily win more than 10 Grand Slam titles in her career

Coco Gauff's rise is unlikely to stop over the next decade, and she will almost certainly end her career with a significant Grand Slam haul.

The WTA Tour is currently at one of the most competitive points in its history. That was shown when four different women won Grand Slams in 2025: Madison Keys at the Australian Open, Gauff at the French Open, Iga Swiatek at Wimbledon, and Aryna Sabalenka at the US Open.

Mirra Andreeva, Victoria Mboko, and Alexandra Eala are young stars who hope to challenge for Grand Slams. However, Gauff will not let that depth stop her from winning several more Major titles.

It has been over six years since Gauff rose to prominence at the 2019 Wimbledon Championships as a 15-year-old. She reached the fourth round at SW19, including a momentous victory against her childhood idol Venus Williams.

Despite being 21, Gauff has been among the WTA's recognizable stars for a significant period. The American finished 2022, 2023, and 2024 ranked No. 3 in the world behind Swiatek and Sabalenka, demonstrating her consistency.

Much of the media coverage surrounding Gauff and the overwhelming expectations placed on her by many often discounts that she is still near the start of her career and will almost certainly get better in the future.

That means Gauff can improve the notable weaknesses she possesses. The most prominent of these is her second serve, as evidenced by the 2023 US Open champion hitting more than 400 double faults in 2025, for the second consecutive season.

Gauff's forehand is also problematic, although on a less dramatic scale compared to her second serve. She hits it with a lot of topspin to provide control, but it stops her from striking as powerfully as several other players.

If the worldwide fan favorite improves those two shots, it will make winning further Grand Slam titles easier. Gauff secured two Major titles while managing those weaknesses, which provides much encouragement for the future.

Almost all American ATP and WTA players are comfortable on hard courts, since most of them grew up on that surface. That applies to Gauff, who began playing tennis on the hard courts in Georgia before moving to Florida for better training opportunities.

Gauff's prowess on hard courts as a professional is demonstrated by her 9-0 win/loss record in WTA finals on the surface. The latest of those triumphs against Jessica Pegula at the 2025 Wuhan Open made her the first woman to win their first nine hard-court singles finals.

However, Gauff has also been an excellent clay court player for a few years. Iga Swiatek's dominance on the surface, including beating Gauff in the 2022 French Open final, stopped her quality on the dirt from being fully appreciated.

That changed when Gauff won this year's event at Roland Garros, beating Aryna Sabalenka in the final. She also dismantled Swiatek 6-1, 6-1 at the 2025 Madrid Open, removing any mental block against the Pole.

Gauff's playing style, which features outstanding movement and a preference for high-bouncing balls on her forehand, arguably makes the 21-year-old even better on clay than on hard courts, even though she is excellent on the latter.

Despite breaking through at Wimbledon, grass is Gauff's weakest surface. However, the American No. 1 can undoubtedly challenge for the other three Grand Slams, and further improvements will improve her hopes at Wimbledon.

Many fans love Gauff for her affable personality and willingness to interact with them. However, that niceness should not be mistaken for an inability to be decisive when the time is right.

Gauff won her maiden Grand Slam at the 2023 US Open under Brad Gilbert's guidance. Twelve months later, she replaced the experienced coach after indifferent results, hiring Matt Daly.

Daly made a swift impact, with Gauff's forehand being noticeably better in her runs to the 2024 China Open and 2024 WTA Finals titles before she also triumphed at the French Open. It seemed like she might have Daly on the team for several years.

Instead, Gauff removed Daly a few days before the 2025 US Open, and hired the biomechanical coach Gavin MacMillan. Those moves were taken specifically to help her second serve, which did not improve during Daly's reign.

Although MacMillan did not have an immediate impact at the US Open, Gauff's second serve got better in her final events of 2025, including in that success at the 2025 Wuhan Open.

Splitting from Gilbert and Daly were brave decisions that some would not have had the courage to make. That ruthless streak and constant want to improve make her chances of winning more than ten Grand Slams even better.
