Coco Gauff’s 2025 US Open journey ended in the fourth round after a tough defeat at the hands of Naomi Osaka, adding another chapter to one of modern tennis’s most compelling rivalries. The two young stars, who first met in 2019, now share an evenly matched record, with each player holding three victories against the other. Their encounters have consistently drawn attention, not only due to their on-court intensity but also because both represent the evolving face of women’s tennis—Gauff with her youthful dynamism and Osaka with her calm power developed under immense pressure.

The rivalry began at the 2019 US Open, a tournament that first introduced many tennis fans to Gauff’s incredible potential. As just a 15-year-old qualifier, Gauff stunned the tennis world by defeating Venus Williams in straight sets during the opening round. Later in that same event, she faced Osaka, then an emerging star who was already famed for her powerful game and two Grand Slam titles. Since that inaugural meeting, they have met multiple times across Grand Slam tournaments and premier events, with high stakes and memorable moments defining their encounters.

At majors, Osaka maintains a slight edge, leading 2-1 in victories over Gauff, including an impressive win at the 2020 Australian Open. That victory came in a tense three-set match where Osaka’s experience helped her edge past the rising star. In contrast, Gauff has shown resilience and growth, often adapting her game and displaying nerves of steel despite her young age.

Gauff’s 2025 US Open campaign had a rocky but promising start. In the first round, she barely escaped a scare against Ajla Tomljanovic. Gauff’s 6-4, 6-7, 7-5 victory was a nail-biter, demonstrating not only her fighting spirit but also occasional vulnerabilities. The second round was even more emotionally charged, as Gauff faced Donna Vekic. Early setbacks, including being broken in the first set, visibly upset her, leading to tears during a changeover—an honest glimpse into the pressures young athletes endure on grand stages. Yet she rebounded spectacularly, channeling her emotions into aggressive and precise play to take the match 7-6, 6-2.

In the third round, Gauff seemed to find her stride, dispatching Magdalena Frech with relative ease and showcasing her improved tactical awareness and versatile shot-making ability. The smooth victory raised hopes among fans and pundits alike that she could continue deep into the tournament, perhaps even reach the quarterfinals or beyond.

But the round of 16 brought Naomi Osaka, who appeared rejuvenated and hungry for success after a period of inconsistency and personal challenges. Osaka’s movement, shot selection, and mental composure were reminiscent of her peak years when she won multiple Grand Slam titles, including the US Open (2018 and 2023) and Australian Open (2019 and 2021). Against Gauff, she applied relentless pressure and forced errors, ultimately securing a commanding 6-3, 6-2 win in just over ninety minutes.

Losers often gain as much respect from their performances as winners do from their victories, and this was certainly true for Gauff. Despite the loss, her determination and maturity were evident throughout the tournament. At just 19 years old, she is still in the earlier stages of what promises to be an illustrious career, and moments like these help build the mental fortitude necessary to compete among the elite for years to come.

Historically, tennis has often showcased rivalries that define generations: from the fierce battles of Martina Navratilova and Chris Evert in the 70s and 80s to the contemporary rivalries of Serena Williams and Venus Williams, and Roger Federer, Rafael Nadal, and Novak Djokovic in men’s tennis. Gauff and Osaka’s rivalry carries echoes of this tradition—a blend of respect, shared history, and contrasting styles that elevate their matches beyond routine competitions.

Navratilova’s insight that “you can’t win if you don’t play, but you can also lose by playing” aptly describes Gauff’s recent US Open run. She showed courage and fight, refusing to ever back down, yet sometimes the experience and tactical prowess of opponents like Osaka prove decisive.

Looking ahead, there is little doubt that Gauff’s story is far from over. After a blink-and-you’ll-miss-it rise to stardom as a teenager breaking through with wins over legends, she continues to mature. Her ability to handle adversity, as observed at this tournament–and in past encounters—suggests she will return stronger and more focused for the next challenge. The women’s tennis landscape is fiercely competitive, but Gauff’s mix of skill, athleticism, and resilience ensures she will remain a key player.

For now, the tennis world waits in anticipation, knowing that every setback is simply a setup for a greater comeback. Coco Gauff’s 2025 US Open exit may be a temporary pause, but if history is any guide, her next chapters will be thrilling to follow.
