Mai Chwalińska’s ascent in women’s tennis has been nothing short of meteoric. The 22-year-old Polish sensation, ranked inside the WTA top 100 for the first time in her career, has captured global attention with her aggressive baseline game, mental toughness, and unrelenting work ethic. Yet, behind the on-court triumphs lie stories rarely seen by fans—stories of health battles, financial sacrifices, and the emotional toll of chasing excellence at the highest level.

In an exclusive conversation with her father, Tomasz Chwaliński, a former professional tennis player and now her coach, the WTA’s rising star opens up about the “hidden struggles” that shaped her journey. From a near-fatal health crisis in 2022 to the relentless grind of training in Poland’s demanding climate, Chwalińska’s path to success is a testament to resilience. This represents the story of what it truly takes to compete at the elite level—and the personal cost of that pursuit.

Chwalińska’s breakthrough in 2024, including her first WTA Tour-level wins and a Grand Slam main-draw appearance at the French Open, has put her in the spotlight. But as her father candidly admits, her road to this moment was far from smooth. “People see the results, but they don’t see the hours of training in the cold, the nights spent recovering, or the moments when she wasn’t sure she’d make it back to the court,” Chwaliński told Polish media earlier this year.

The Health Battle That Nearly Ended Her Career

In late 2022, Mai Chwalińska’s world nearly collapsed. What began as persistent fatigue and unexplained weight loss escalated into a medical mystery that kept her off the court for nearly six months. Initially diagnosed with a viral infection, doctors later identified a more complex underlying condition—one that required a radical adjustment to her lifestyle and training regimen.

According to Poland’s National Tennis Federation (PZPN), Chwalińska’s condition was severe enough to prompt a temporary suspension of her competitive schedule. “She was at a breaking point,” her father revealed in interviews. “There were days when she couldn’t even stand up for more than a few minutes. The mental strain was just as hard as the physical.”

The recovery process involved a multidisciplinary approach: nutritional adjustments, specialized physiotherapy, and a complete overhaul of her training intensity. Chwaliński, who had already retired from professional play, took on a more hands-on role in managing her daughter’s health, even consulting with sports medicine experts in Germany and the Czech Republic. “We had to learn everything from scratch—what foods she could tolerate, how much sleep she needed, even how to structure her day so she didn’t overexert herself,” he said.

From Crisis to Comeback: The 2023 Turnaround

Chwalińska’s return to competition in early 2023 was cautious but deliberate. She started with ITF tournaments in Poland and Slovakia, gradually rebuilding her endurance and match fitness. By mid-year, she had regained her rhythm, winning two ITF titles and earning a wildcard into the Wimbledon qualifying draw. Though she fell short in the final round, her performance signaled a full recovery.

The breakthrough came in late 2023 at the Luxembourg Open, where she claimed her first WTA Tour title. The victory was emotional—both for Chwalińska and her father, who had watched her struggle through the previous year. “That win wasn’t just about tennis,” Chwaliński said. “It was about proving to herself that she could come back stronger.”

“She lost a year of her life to this illness. When she walked onto that court in Luxembourg, it wasn’t just about the trophy—it was about reclaiming her future.”

The Financial and Emotional Toll of Elite Tennis

Behind every professional athlete’s success story lies a network of unseen sacrifices. For Chwalińska, this includes the financial burden of training at the highest level in a country where tennis infrastructure is still developing. Unlike players from tennis powerhouses like the U.S. Or Spain, Chwalińska has relied heavily on her father’s resources to fund her career.

Tomasz Chwaliński, a former player himself, has acted as both coach and financial backer, covering travel costs, coaching fees, and equipment. In interviews, he has acknowledged the strain this has placed on their family. “We’ve had to make tough choices—delaying other investments, taking on extra work,” he said. “But when you see your daughter’s face light up after a win, it’s worth every penny.”

The lack of sponsorship deals for Polish players adds another layer of pressure. While Chwalińska has secured partnerships with local brands like PZPN-affiliated companies, she remains far behind her peers in terms of commercial revenue. This reality has forced her to focus on prize money and limited exhibition matches to supplement her income.

A Father’s Role: Coach, Mentor, and Emotional Anchor

Tomasz Chwaliński’s influence on his daughter’s career extends beyond tactics. As her primary support system, he has navigated the dual roles of disciplinarian and cheerleader—a balance that becomes even more critical during setbacks. “There were moments when she wanted to quit,” he admitted. “Not because she didn’t love tennis, but because she was exhausted. That’s when I had to remind her why she started this journey in the first place.”

His coaching philosophy centers on mental resilience. “In tennis, your opponent is often yourself,” he often tells her. “The ability to stay focused when everything is going wrong—that’s what separates the solid players from the great ones.” This mindset has been tested repeatedly, including during her early-round exits at Grand Slams, where the pressure to perform under scrutiny is immense.
