Guga’s ascent to tennis supremacy: 25 years since Gustavo Kuerten conquered the world
Gustavo Kuerten. The name alone stirs a memory of bright hair, a mass of dirty-blond curls, and an infectious, unstoppable smile that brightened every brutal rally. He carried a joy for the grind of tennis and a forehand that would reshape the game. Twenty-five years ago this week, that combination—talent, confidence, and a coach’s firm belief in a destiny Brasileño players had yet to claim—launched Kuerten to the world No. 1 ranking. He remains the only Brazilian to reach the pinnacle under the current ATP rankings system (established in 1973), and, until now, the sole South American to do so. Since then, none have matched that feat.
“The history books aren’t friendly to these paths,” Kuerten, now 49, reflected recently from his Florianópolis headquarters, where his business and foundation operate. “We had an example to follow in Maria Esther Bueno,” he noted, honoring the legendary No. 1 in women’s tennis from the 1950s and 1960s who won seven Grand Slam singles titles before professionals were allowed to compete. “But it was mostly hidden. Nobody fed you these beliefs openly.”
A quarter-century after reaching tennis’s summit, Kuerten’s life has changed in many ways, yet much remains the same. His hair still curls, the smile still shines, and his drive to succeed endures. He now has an artificial hip and plays tennis only about six times a year because the act of balancing and pushing off on one leg can be painful. His 12-year-old son, Luis Felipe, is emerging in Brazil’s junior ranks, carrying the Kuerten tennis legacy forward.
“It’s much harder to stay at No. 1,” Gustavo admits. “Hopefully, in a few years, I can return to enjoying the moment more fully.”
A typical day begins with a few hours of exercise, often including his beloved surfing, followed by physical therapy. Then he heads to the office to handle work for his business or his foundation, which champions social inclusion and transformation through sports and the arts for children, especially those with disabilities. Kuerten’s family story includes his younger brother Guilherme, who lived with cerebral palsy and passed away in 2007. Guilherme was a source of light for the family and the keeper of Gustavo’s trophies. He never accompanied Gustavo to the airport when journeys began because it broke his heart to see his brother go, yet he always welcomed him back home with the hardware in hand.
Later in the afternoon, Kuerten shifts into dad mode, driving his son to tennis practice or his daughter Maria Augusta to piano lessons. It’s a life filled with laughter and warmth.
The moments of triumph flood back most vividly when he recalls the start of his journey: 1992, during his first French Open visit as a 15-year-old with more on his plate than orbiting expectations. In a postcard he sent home, he promised to practice relentlessly and someday become No. 1, writing it down to cement the belief.
At the 1997 French Open, Kuerten clinched his first title, riding a topspin forehand to victory. That same year, he made a pivotal technical leap: he was among the early adopters to switch from natural gut to polyester strings. The new material allowed bigger, longer swings, greater racket speed, and more spin, enabling power and consistency in equal measure. Kuerten embraced this technology at 17 and built the rest of his game around it.
Entering Roland Garros in 1997 as world No. 66, he left with his first Grand Slam trophy, defeating three of the sport’s recent champions on the way: Muster in the third round, Kafelnikov in the quarterfinals, and Bruguera in the final. That triumph vaulted him into the top 15, yet he remained distant from the sport’s top echelon, where Pete Sampras and a rising wave of legends already loomed.
The quest to reach No. 1 over the next few years meant overcoming formidable rivals: Angelic lineups featuring Michael Chang, Yevgeny Kafelnikov, Patrick Rafter, and the ascendant Andre Agassi, all challenging the dominance of Sampras. Even after 1999, Kuerten stood above Sampras and Agassi only briefly, with the American pair still seeming to exist in a different plane.
A defining moment arrived in 2000 at the Miami Open final, where Kuerten and Sampras dueled in a match decided by a trio of tiebreaks, of which Sampras captured two, including the decisive one 8-6. On the flight home, the coach who had guided him, Larri Passos, pressed a crucial question: “You are ready to be No. 1.” Initially met with doubt, Kuerten’s confidence had already begun to crystallize after testing the upper echelon in earlier matches.
Two months later, he defended his clay mastery by claiming titles in Hamburg and Paris, beating Kafelnikov again, Ferrero, and Norman, fighting back from a fierce late rally by the Swede. The public’s imagination fixated on Kuerten’s distinctive curls, electric smile, and relentless forehand, and the sport began to imitate his approach, including the adoption of polyester strings.
A hard-court title in Indianapolis followed, yet the U.S. Open saw a first-round exit. By the year’s end, Kuerten stood as world No. 2 heading into the ATP Tour Finals, where he defeated both Agassi and Sampras to seize the crown and become No. 1. He would hold that position for 43 weeks over the next year before ceding it to Lleyton Hewitt in November 2001.
Kuerten isn’t surprised that South America hasn’t yielded another No. 1 since: the era’s all-encompassing competition from players like Federer, Nadal, Murray, and Djokovic, plus the emergence of stars such as Sinner and Alcaraz, has kept the bar incredibly high. Juan Martín del Potro remains the continent’s last Grand Slam singles champion, reaching No. 3 at his peak.
“Even for the United States, it’s rare,” Kuerten notes.
The obstacles Kuerten faced weren’t unique. Brazil and South America have long struggled with tennis infrastructure compared with Europe and North America. Today, the circuit’s February South American swing gradually loses ground as the ATP Masters 1000 event in Saudi Arabia promises to draw more attention and resources away from the region. ATP Tour chairman Andrea Gaudenzi has suggested the new event should occur alongside programs in South America.
Kuerten believes the next South American challenger could rise soon: João Fonseca, a 19-year-old Brazilian sensation whose surge has drawn crowds worldwide, echoing the wave Kuerten once rode. As Fonseca’s profile grows, Kuerten remains available as a mentor, though he proudly defers to the excellent coaching already shaping Fonseca’s development with Guilherme Teixeira. He aims not to interfere, choosing instead to observe from the background.
“Mindset is the decisive edge,” Kuerten explains. “What matters is his hunger for the game and his drive to reach the maximum.” Fonseca’s background is comfortable, even before prize money or sponsorships. Kuerten contends that many players pursue the easy life of wealth and fame, but Fonseca seems driven by something more. He doesn’t expect a breakthrough next year, but suggests a three- to five-year horizon.
Perhaps the family’s next chapter will include Kuerten’s son, too. Passos plans a trip to Brazil from Florida to conduct a training camp in December, and Luis Felipe will attend—a potential new chapter for South American tennis dreams.
