MIAMI/WASHINGTON, March 21, 2026 (by Michael Dickens)
Brazil’s Joao Fonseca has become a sporting hero for his nation – and his legion of fans can’t get enough of him. They’ve followed the teenage wonder through the Golden Swing of South America to the United States, first packing the stands at the Indian Wells Tennis Garden during the recent BNP Paribas Open and this week at Hard Rock Stadium in Miami Gardens for the Miami Open presented by Itau.
Fonseca, a 19-year-old native of Rio de Janeiro with two ATP Tour titles to his name, has been receiving a top-notch education on the world’s tennis courts he won’t soon forget. Earlier this month, after securing a pair of Top-25 wins in the California palm desert against Russia’s Karen Khachanov and Tommy Paul of the United States, Fonseca went cara a cara with World No. 2 Jannik Sinner last week in a slugfest decided by a pair of tiebreakers that went in favor of the 24-year-old Italian star, 7-6 (6), 7-6 (4). Fonseca let slip a set point but certainly gave a good account of himself in defeat.
Then, 10 days later in South Florida, with boisterous support from Miami’s Brazilian community – one of the largest contingents of Brazilians living in the United States – who filled the 13,000-seat temporary stadium court constructed inside cavernous Hard Rock Stadium, the 39th-ranked Fonseca took on the World No. 1 Carlos Alcaraz for the first time Friday night. Many of Fonseca’s fans were sporting familiar Brazilian football jerseys and waving colorful Brazilian flags.

Although the 22-year-old, seven-time major champion from Spain won 6-4, 6-4, in one hour and 35 minutes, thanks in part to his experience and maturity in the biggest moments, Fonseca showed under the big spotlight that he belonged in the moment. Just a couple of service breaks – early in both sets – decided the outcome and, arguably, Alcaraz handled the pressure-filled moments a little better than Fonseca.
“I think I was really good in crucial moments. I was really good since the beginning until the last ball. I know how good Joao is, and that’s why I was really focused, every point, every shot,” Alcaraz said after the match.
Looking back, there were plenty of spirited rallies between the two on the court – and the Davis Cup-like atmosphere contributed to the excitement of the night. Both players seemed to welcome – and, at times, thrived on – the lively applause from the crowd throughout the duration of their 130-point second-round match.

During this year’s Sunshine Double, Fonseca has learned plenty on the court that will help to make him a better player in the future. At the very least, he’s finding out first-hand what makes each champion’s game different. He spoke to the media about the differences between Alcaraz and Sinner afterward.
“I think Alcaraz has more arsenal than Sinner. Sinner is more like a robot that just kills the ball and does everything perfect,” Fonseca said after Friday night’s loss to Alcaraz, during his post-match news conference. “Carlos, he can do everything. He can do with topspin, can fire the ball, he has good movement. Goes to the net. He has everything. It’s more difficult to understand the game. He breaks a lot your rhythm.”
Alcaraz outpointed Fonseca 72-58. He won 71 percent (45 of 63) of his service points and 40 percent (27 of 67) of his receiving points, both higher percentages than Fonseca. Alcaraz struck 27 winners – including eight aces – and converted two of five break points. Fonseca countered with 13 winners, made 20 unforced errors and went 0-for-3 in break-point opportunities. Alcaraz improved to 13-0 against players younger than him and he’s 17-1 overall this year. Meanwhile, Fonseca’s win-loss record for the still-young 2026 season dropped to 5-5 after starting 1-3.
“I think Jannik’s game helped me to enter the court with no fear, trying to play my game,” Fonseca added. “But I think I didn’t get the opportunities that I had, and of course he played well. He’s No. 1 in the world. But I need to think about my mistakes and try to improve.”

Fonseca explained how Alcaraz’s experience enabled him to break the young Brazilian’s rhythm of rallies through the use of slice, topspin and angles.
“He has most of everything,” he said. “So, you don’t know what’s coming, and if it’s coming serve, serve and volley, if it’s going serve wide and do a plus-one shot, you kind of don’t know.
“So that’s the difficulty of playing against him. You need to almost play a perfect match.”
Meanwhile, Alcaraz said he enjoyed facing Fonseca for the first time and praised him after the match.
“It feels like he can make a winner from everywhere. And that’s impressive,” he said. “That’s what surprised me the most. But at the same time, I know what he’s capable of doing. Great shots, great power. …
“For him, playing toe to toe with us, I think he and his team are going to get great feedback to know what he should improve in the future,” Alcaraz added. “I think he has everything, great shots, a lot of things to improve, but for sure he’s going to do it. Back-to-back tournaments playing the No. 1 and No. 2 in the world, I think it’s going to be really helpful for him.”

Last week in Indian Wells, after Sinner defeat Fonseca, the South Tyrolean spoke positively of the Brazilian hopeful.
“Well, I think he is fearless. He likes to go for shots. He is very aggressive. Has a great mentality. You know, I feel like he’s … in really good hands with his team. They are having very positive approach, you know, of tennis, which this is very important for especially young players.
“I don’t know him very well off the court, but he seems like a humble kid, humble player. Yeah, for sure he’s going to be very, very tough to beat. He’s already very tough to beat, but even in the future, even more so.
“It’s good. It’s good for the sport. It’s definitely good for the sport having him …”

Whether Fonseca represents the next player who can challenge Alcaraz and Sinner – and win – remains to be seen. However, Fonseca looks forward to the challenge of facing the World No. 1 and No. 2 players. Certainly, he possesses the power in his groundstrokes and the potential in his all-around game to beat both. After winning the Next Gen ATP Finals title in 2024, Fonseca has shown he has the all-around game to win regularly on the ATP Tour – and he welcomes taking it to the next level.
And guess what? The ATP Tour certainly welcomes the opportunity to market Fonseca to a world-wide audience – part of the up-and-coming group of Next Gen of ATP rising stars that also includes Jakub Mensik of Czechia and American Learner Tien, as well even younger hopefuls like 17-year-old Moise Kouame of France and 18-year-old Darwin Blanch of the United States, both of whom won their first-round matches in Miami. One thing is certain: It’s safe to say that Brazilian fans certainly will be there in big numbers cheering for their own charge, Fonseca, wherever he’s playing in the world – and that’s a positive for men’s pro tennis.
Win or lose, Fonseca called his match against Alcaraz a “fun” one. “He played some amazing shots,” Fonseca said. “It was entertaining, and I think was good for the crowd.”
