João Fonseca, the 19-year-old Brazilian talent, steps onto the Laver Cup courts for the first time representing Team World. The event, held at the Chase Center in San Francisco, marks a historic moment for the Rio native, who becomes the youngest competitor in the tournament’s history since its inception in 2017. With a current ATP ranking of 42nd, Fonseca arrives after a season of rapid ascent, including Challenger victories and advances in Grand Slams.
The debut match takes place this Friday, September 19, at 11 PM Brasília time, against Italian Flavio Cobolli, ranked 25th. The clash opens the night session and promises intensity, as the two faced off in June at the ATP 500 in Halle on grass, where Cobolli won 5/7, 7/6(3), 7/6(8) in nearly three hours. Now, on indoor hard court, Fonseca aims to reverse the score.
The Laver Cup, envisioned by Roger Federer in homage to Rod Laver, gathers six players per team in singles and doubles matches over three days. Wins are worth one point on Friday, two on Saturday, and three on Sunday, with the first team to reach 13 points claiming the trophy. Team World, captained by Andre Agassi, features Patrick Rafter as deputy, while Team Europe is led by Yannick Noah and Tim Henman.
- Team World: Taylor Fritz (USA, 5th), Alex de Minaur (AUS, 8th), Francisco Cerúndolo (ARG, 20th), Alex Michelsen (USA, 43rd), Reilly Opelka (USA, 32nd), and João Fonseca (BRA, 42nd).
- Team Europe: Carlos Alcaraz (ESP, 2nd), Alexander Zverev (GER, 3rd), Holger Rune (DEN, 11th), Casper Ruud (NOR, 12th), Jakub Mensik (CZE, 16th), and Flavio Cobolli (ITA, 25th).
- Alternates: Tomáš Macháč (CZE) for Europe and Jenson Brooksby (USA) for World.
Encounter with Federer boosts Fonseca’s motivation
Fonseca could barely contain his excitement upon meeting Roger Federer, his idol, during practices at the Chase Center. The Swiss, co-creator of the tournament and present at his 2022 retirement in London’s Laver Cup, posed for photos with the Brazilian, who admitted to sweaty palms from nerves. This moment, which occurred on Tuesday, September 16, underscores how the event transcends sport for the 19-year-old.
Agassi, the American legend with eight Grand Slams, slotted Fonseca into the opening singles at night, ensuring his mandatory participation in the first two days. The captain highlighted the Brazilian’s aggressive mindset, which shines in decisive moments, like his win over Andrey Rublev at the 2025 Australian Open. For Fonseca, playing alongside Fritz and de Minaur represents a practical lesson in handling high-level pressure.
The Chase Center, home to the Golden State Warriors, transforms into a tennis arena with a black court and white lines, dramatic lighting, and a show-like atmosphere. With capacity for 18,000 spectators, the venue draws fans from the Bay Area, known for its passion for innovative sports. The 2025 edition marks the first time in the US since 2022 in Boston and promises attendance records.
Fonseca’s preparation included visits to Oracle Park, the Giants’ stadium, where he tested skills in baseball, showing versatility off the court. His teammates, like Cerúndolo, with whom he shared the bench in Buenos Aires, praised his contagious energy. The Argentine, undefeated in two prior Laver Cups, sees the Brazilian as an ideal doubles partner.

Head-to-head history shapes strategies for the matchup
Cobolli, a 23-year-old left-hander with a two-handed backhand, grew up on Italian clay but adapted well to grass in Halle, saving a match point against Fonseca. The Florentine Italian leaped into the top 30 in 2025 with Masters 1000 semifinals and an ATP 500 final. His patient game, with rhythm variations, contrasts with Fonseca’s explosive forehand, which dictates quick points.
In Halle, Fonseca took the first set 7/5, but Cobolli rallied in the subsequent tie-breaks, capitalizing on the Brazilian’s unforced errors in the third set. Now, on indoor hard, Fonseca plans more aggression on serve, where he averages 12 aces per match this year. The Italian, meanwhile, bets on baseline consistency, with 78% of points won on long returns.
The Laver Cup demands quick adaptation, as each player must compete in at least one singles in the initial days, and four per team in doubles. Fonseca, who won the 2024 Next Gen ATP Finals as the only South American, draws on that experience to absorb Agassi’s lessons on mental focus. Coach Marcelo Velloso, present in San Francisco, adjusted drills to neutralize Cobolli’s slice.
Season data shows Fonseca with 28 wins in 42 matches, including titles in Buenos Aires and two Challengers. Cobolli tallies 32 victories in 48 outings, highlighted in Hamburg. These figures indicate balance, but the home factor for Team World could tip the scales.
- Fonseca in 2025: 5-2 in Grand Slams, including third round at Roland Garros and Wimbledon.
- Cobolli in 2025: Quarterfinals in Miami and Indian Wells, with 65% win rate on hard courts.
- Prior matchups: One game, Cobolli’s win on grass; no hard court history.
- Key serves: Fonseca converts 45% of break points; Cobolli defends 68% of his.
Laver Cup format requires balance between singles and doubles
The tournament follows the inverted pyramid of sports journalism: initial actions set the pace, with daytime and nighttime sessions. On Friday, Casper Ruud faces Reilly Opelka at 5 PM, followed by Jakub Mensik against Alex Michelsen. After Fonseca vs. Cobolli, Alcaraz and Mensik duel in doubles with Fritz and Michelsen. Saturday and Sunday lineups remain to be set, but each athlete plays at most two singles.
Progressive scoring heightens tension: one point today could be crucial if the score tightens at the end. Team Europe leads the history with five titles in seven editions, including 2024 in Berlin by 13-11. Team World won in 2022 and 2023, with McEnroe as former captain. Agassi, now in charge, brings expertise from 1990, when he led epic comebacks.
Fonseca, who broke into the top 100 in February after beating Rublev, views the Laver Cup as a bridge to future major seeding. His 2025 US Open ended in the second round against Tomas Machac, but the lessons propel him. In the tournament, he trains with Cerúndolo, whom he defeated in Buenos Aires, strengthening Team World bonds.
Broadcast in Brazil airs on ESPN and Disney+, with full three-day coverage. Fans follow via app, with reserve bench radio feeds. The event features merchandise pop-ups, like Wilson RF01 rackets and On Roger Clubhouse sneakers, exclusive to the edition.
Fonseca’s preparation reveals Agassi’s lessons
Andre Agassi, icon with a 101-title career, guides Fonseca in visualization sessions, emphasizing breathing in tie-breaks. The American, who retired in 2006, compares the young player to himself in the 1980s for his boldness. Morning drills at the Chase Center included volley practice, prepping for potential doubles with de Minaur.
The Australian, top 10, praised Fonseca as “the future of tennis,” excited to see him shine. Cerúndolo, 2-0 in Laver Cups, shares tips on collective pressure, different from the individual circuit. Opelka, a 6’11” giant, jokes about serves against Ruud, easing team tension.
Fonseca, born in 2006 in Rio, started tennis at five, influenced by his athletic family. His parents, Roberta and Christiano, practiced various sports, and frequent visits to the Rio Tennis Center shaped his passion. In 2023, as a junior, he won the US Open and reached world No. 1, the first Brazilian in that spot.
His 2025 breakout includes direct qualification for the Australian Open, where he stunned Rublev 6-4, 6-3, 7-5. At Roland Garros, he reached the third round, falling to Stefanos Tsitsipas. Wimbledon repeated the feat, eliminated by Jannik Sinner. These results lifted his ranking from 65th to 42nd.
Rivalry between teams takes on personal contours
Team Europe, with Alcaraz fresh from the 2025 US Open, seeks a sixth title. The Spaniard, No. 2, beat Fritz in the 2024 final, securing the trophy. Zverev, 3rd, adds doubles-winning experience. Rune and Ruud bring consistency, while Mensik, 16th, and Cobolli represent renewal.
For Team World, Fritz, Paris 2024 Olympic bronze medalist, leads with 12 aces per game. De Minaur, speedy, complements with aggressive returns. Michelsen and Opelka add power, and Cerúndolo stability. Fonseca, as the youngest, injects freshness, with a forehand hitting 140 km/h.
The indoor court, with a sand layer for longer rallies, favors extended exchanges. Best-of-three sets uses ad scoring and a 10-point tiebreak in the third. Each singles lasts up to two hours, doubles one and a half. ATP umpires ensure impartiality.
Fonseca practices with jumbo yellow balls for accuracy, and yoga sessions for flexibility. Velloso, his supervisor, monitors post-US Open recovery, where Fonseca ran 15 km in two matches. Nutrition includes high carbs for sustained energy.
- Fonseca’s strategies: More net approaches, aiming for 70% forehand points.
- Cobolli’s weaknesses: 35% unforced errors on long serves.
- Team World support: Agassi focuses on “attack without doubt,” Fonseca’s Buenos Aires phrase.
- Crowd expectation: 15,000 tickets sold for Friday, with Brazilian fans in the Bay Area.
Chase Center atmosphere elevates the spectacle
The Chase Center, opened in 2019, adapts to tennis with a 74×42-foot LED screen for replays. Fans access Fan Radio via app, hearing captain commentary. Interactive areas include mini-USTA courts for kids, with free instruction.
Exclusive merchandise, like Laver Cup logo caps and giant balls, fills stores. Limited-edition On Roger sneakers attract collectors. Outside the arena, Thrive City offers food trucks with Californian dishes, blending local culture into the event.
Fonseca, a basketball fan, visits the Warriors’ gym during downtime, drawing inspiration from team grit. Agassi, who played packed arenas, reminds him: “The crowd is an ally on the team.” With a mixed crowd but extra support for World as hosts, the noise could sway breaks.
The Laver Cup promotes inclusion, with wildcards for emergents like Fonseca. His invitation, announced in May, generated global buzz, with 500,000 views on announcement videos. For the Brazilian, it’s a networking chance, swapping shirts with Alcaraz post-match.
The tournament ends Sunday at 6 PM local time, with overtime if tied at 12-12: doubles with a decisive tiebreak. History shows comebacks, like 2024, where Europe reversed 7-11. For 2025, balance suggests a tight fight to the finish.
