On a night defined by resilience and emotion, young Brazilian tennis player João Fonseca, just 18 years old, kicked off his Miami Open campaign with a victory in the Masters 1000 tournament held in the United States. Facing American Learner Tien, ranked 66th in the world, Fonseca pulled off an impressive comeback, winning 2-1 in sets with scores of 6/7 (1), 6/3, and 6/4. The match, played on Thursday, went beyond a typical tennis showdown: the Rio de Janeiro native battled nausea in the third set but leaned on the vibrant support of the Brazilian crowd to secure his spot in the next round. Meanwhile, Bia Haddad Maia suffered an early exit, and Luisa Stefani advanced in doubles, keeping Brazil’s presence alive in the competition.
João Fonseca’s triumph underscores his rising momentum, fresh off a title win at the Phoenix Challenger last week. Currently ranked 60th in the ATP standings, he showcased not only technical skill but also mental toughness in overcoming physical adversity. His clash with Tien, aged 19, pitted two rising stars of the sport’s new generation against each other, reigniting a rivalry last seen in the 2024 Next Gen ATP Finals final, which Fonseca also won.
The Brazilian contingent in the tournament experienced a mix of highs and lows. Bia Haddad Maia, ranked 18th in the WTA, fell in her opening match to Czech player Linda Fruhvirtova, ranked 215th, with a score of 6/0, 6/2. On a brighter note, Luisa Stefani, paired with Hungary’s Timea Babos, started strong in doubles, defeating Ulrikke Eikeri and Giuliana Olmos 6/3, 6/4 to reach the round of 16.
A debut packed with challenges for João Fonseca
João Fonseca stepped onto the court determined to make an impact at the Miami Open, and his aggressive intent was clear from the start. In the second point of the match, he unleashed a powerful forehand, signaling his readiness to dictate play. He earned three break points in the opening game, securing an early break against Tien. However, the American responded swiftly, leveling the set in the third game after Fonseca misfired at the net with an open court. The first set remained tight, with Fonseca leading the offensive charge while Tien relied on varied serving and defensive patience to force errors. Despite two break point chances at 5-5, Fonseca faltered in the tiebreak, where Tien surged to a 6-0 lead and closed it out 7/1 after 56 minutes.
The second set saw Fonseca recalibrate. Dialing back the adrenaline, he stayed composed and capitalized on Tien’s dip in form, particularly the American’s loss of serving precision—a key strength in the prior set. Two double faults from Tien handed Fonseca a 3-1 lead, which he solidified with a hard-fought service game marked by lengthy rallies. Holding firm against Tien’s resistance, the Brazilian clinched the set 6/3, leveling the match and setting the stage for a decisive third set.
That final set turned into a test of grit. With the score at 2-1 in his favor, Fonseca’s physical strain became evident as he signaled nausea to the chair umpire, prompting a medical timeout. The Brazilian crowd roared louder, creating a home-like atmosphere that rattled Tien. The American buckled under pressure, committing two uncharacteristic errors to surrender a break. After receiving treatment, Fonseca returned revitalized, sealing a 40-0 service game with two stunning points—one a back-to-the-net defensive gem. Despite a near ankle twist late in the set, he held on to win 6/4, sealing a hard-earned victory.
Bia Haddad Maia disappoints with early exit
Bia Haddad Maia’s Miami Open journey was short-lived. The world number 18 faced 19-year-old Linda Fruhvirtova and struggled mightily, falling 6/0, 6/2 in straight sets. The match laid bare the Brazilian’s ongoing rough patch in 2025, with a performance far below her usual standard. In the first set, she racked up 20 unforced errors and managed just 20% of points on her first serve, succumbing in a mere 24 minutes.
Showing resolve, Haddad Maia opened the second set with a 40-0 game win, briefly hinting at a turnaround. Yet, Fruhvirtova stayed unfazed, breaking the Brazilian’s serve to lead 3-2 and quickly extending it to 5-2. In the final game, the Czech player overcame a double fault to reach match point, sealing her victory with an ace as Haddad Maia faltered once more. The upset loss to a player ranked 215th underscores a challenging moment for Brazil’s top female player.
Luisa Stefani keeps Brazil alive in doubles
Amid Fonseca’s triumph and Haddad Maia’s defeat, Luisa Stefani offered a bright spot for Brazilian fans. Teaming up with Timea Babos, she opened her doubles campaign with a convincing 6/3, 6/4 win over Norway’s Ulrikke Eikeri and Mexico’s Giuliana Olmos. The duo’s synergy shone through, propelling them to the round of 16. Stefani, ranked 32nd in doubles, continues her comeback from past injuries, aiming to reclaim her place among the elite in the discipline.
Their next opponents will be the winners of the matchup between Monica Niculescu/Katarzyna Piter and Elise Mertens/Zhang Shuai. The victory provides a boost for Stefani and Babos, who are looking to make a deep run in Miami and build on their promising partnership.
What’s next for the Brazilians at the Miami Open
Following Thursday’s results, João Fonseca and Luisa Stefani carry Brazil’s hopes forward. Here’s a look at their upcoming challenges:
- João Fonseca vs. Ugo Humbert: Fonseca takes on the 26-year-old Frenchman, ranked 20th, in the second round. Humbert, who received a first-round bye, brings experience, but Fonseca’s momentum and crowd backing could make it a close contest.
- Luisa Stefani/Timea Babos: In doubles, the pair awaits the outcome of Niculescu/Piter vs. Mertens/Zhang to determine their round-of-16 opponents.
Running from March 18 to 30, the Miami Open is the second leg of the Sunshine Double, following Indian Wells. For Fonseca, it’s a chance to climb further in the ATP rankings, while Stefani aims to solidify her doubles credentials.
Key stats and highlights from the Brazilian performances
The opening round delivered a mix of standout moments and surprises for Brazil. Here are some notable figures:
- Fonseca won 63% of first-serve points in the third set, even while battling nausea.
- Haddad Maia lost five of seven service games against Fruhvirtova.
- Stefani and Babos converted 3 of 5 break points in their doubles win.
- The Brazilian crowd’s energy was a game-changer, with Fonseca likening it to playing at home.
Fonseca’s win also extended his perfect 2-0 record against Tien in 2024, while Haddad Maia’s loss marked her sixth straight defeat on the WTA tour.
The future of Brazil’s tennis generation
João Fonseca is emerging as one of Brazil’s brightest tennis prospects in years. At 18, with a Challenger title and now a Masters 1000 win under his belt, his ability to perform under pressure—physical or otherwise—hints at a stellar career ahead. His next match against Ugo Humbert will be a critical gauge of his readiness to compete with the world’s best.
Bia Haddad Maia’s early exit raises concerns about her current form. After a rollercoaster 2024, she must rediscover the consistency that made her a top-20 player. With the Billie Jean King Cup looming in April, the pressure is on to regroup. Meanwhile, Luisa Stefani remains a steady force in doubles. Her run in Miami could propel her ranking higher, rewarding her resilience after injury setbacks.
