Coco Gauff and Caty McNally share a remarkable story in professional tennis—one that blends friendship, trust, and an impressive display of skill on the court. Their journey together began in the junior ranks and blossomed into a partnership that captured the attention of tennis fans worldwide, highlighting how sport can forge deep personal connections as well as competitive success.

Coco Gauff, born in 2004 in Delray Beach, Florida, quickly rose to prominence as one of tennis’s brightest young stars. She made headlines at a young age, famously defeating Venus Williams at Wimbledon in 2019 when she was just 15. Around the same time, Caty McNally, born in 2001 in Cincinnati, Ohio, was building her own promising career, known for her aggressive play and net skills. Their paths converged in 2018 when the young pair teamed up at the Junior French Open (Roland Garros). There, they captured the Junior Girls’ Doubles title, a milestone that marked the beginning of a significant doubles partnership.

Their success in juniors was no fluke. Gauff and McNally quickly transitioned to the WTA circuit, where their youthful energy and complementary styles made them a formidable team. Their strong chemistry on court became a signature element of their play. Gauff’s powerful baseline game paired beautifully with McNally’s deft touch at the net. This synergy propelled them to WTA doubles titles, including two titles in 2019 at the Lexington Open and the Citi Open in Washington, D.C. Their performances captivated fans, signaling the emergence of a new generation ready to challenge established doubles teams.

Beyond their titles, the bond between Gauff and McNally stood out. They referred to each other not just as partners, but as close friends—almost like sisters. This closeness helped them navigate the pressures and anxieties that come with professional tennis. For young athletes thrust into the spotlight early, having a trusted teammate who understands the highs and lows can be crucial. Late-night conversations, shared travel experiences, and mutual support off the court deepened their connection, highlighting how friendship often extends beyond sport.

Historically, tennis has seen famous doubles partnerships built on friendship and trust—think of the Williams sisters or the Bryan brothers—where understanding each other’s rhythms and mindsets becomes just as important as technical skills. Gauff and McNally fit into this tradition, bringing a fresh, youthful energy to the doubles scene.

However, relationships and partnerships in professional sports do evolve. In August 2022, Gauff and McNally announced that they would no longer play doubles regularly together on the WTA Tour. While the break surprised some fans, the parting was described as amicable, with both young women emphasizing the importance of their ongoing friendship. McNally explained that even though their professional paths might be diverging to focus more on singles or other partnerships, their support for each other remained steadfast.

Their story also intersects with team competitions, exemplified by events like the Billie Jean King Cup—formerly called the Fed Cup—which pits countries against each other in high-stakes matches. Gauff and McNally have continued to represent the United States in these competitions, occasionally pairing up for doubles matches, showing that despite changes in their tour scheduling, their bond on the court endures.

To appreciate the significance of their partnership fully, it helps to consider the broader context of tennis doubles. Doubles has often been overshadowed by singles, but it requires a unique set of skills: synchrony, communication, and mutual trust. Historically, some of the most legendary tennis partnerships emerged because players understood each other perfectly. The Bryan brothers, for instance, dominated men’s doubles for over a decade, partly because of their lifelong sibling bond. Similarly, Venus and Serena Williams’ doubles success was fueled by their sisterly connection. In this lineage, Gauff and McNally represent a modern, youthful exemplar of how friendships can fuel athletic performance.

Looking ahead, both players are expected to continue growing their singles careers, with Gauff already making deep runs in Grand Slam tournaments. Nonetheless, their doubles partnership remains a bright and inspiring chapter in their careers. Whether they reunite regularly on court or continue to support each other from different singles campaigns, their story serves as a testament to the power of friendship in competitive sports.

Their journey also reminds us of the evolving nature of tennis careers. Young players often experiment with doubles early on to gain experience and confidence, then transition to focusing more heavily on singles. This balancing act is part of what makes following young talents so intriguing. Gauff and McNally exemplify the modern tennis player who embraces versatility—competing at the highest levels in both singles and doubles, while nurturing friendships that transcend the sport.

Coco Gauff summed it up perfectly when she said, “We may not always be doubles partners, but we’ll always have each other’s backs—just like in tennis, where you’ve got to trust your partner to cover your back.” Their partnership, although occasionally interrupted by shifting priorities, continues to be a remarkable example of trust, friendship, and passion in the fast-paced, often solitary world of professional tennis. Together, they have already made their mark on the sport, and their enduring friendship promises many more exciting chapters ahead.
