There is little doubt that Carlos Alcaraz and Jannik Sinner are in a league of their own in men’s tennis at the moment, and Brazilian teenager Joao Fonseca had the privilege -- and daunting challenge -- of facing them within 10 days during the Sunshine Double.
At Indian Wells, Fonseca met Sinner in the round of 16 and suffered a narrow 7-6 (6), 7-6 (4) defeat in a tightly contested encounter. At the Miami Open, the draw paired him with world number one Alcaraz.
The Spaniard defeated the 19-year-old 6-4, 6-4 on Friday night in their first-ever ATP Head-to-Head meeting, with both players showcasing aggressive tennis. Fonseca received strong backing from Brazilian fans but ultimately fell short as Alcaraz’s experience, class, and maturity proved decisive.
Speaking after the match, Fonseca reflected on the contrasting challenges of facing the top two players in quick succession.
“I think it [facing Jannik Sinner at Indian Wells] helped me to understand… of course, it’s different types of games. I think Alcaraz has more arsenal than Sinner. Sinner is more like a robot that just kills the ball and does everything perfect. Carlos, he can do everything. He can do with topspin. He can fire the ball. He has good movement, he goes to the net. He has everything,” Fonseca said in the press conference.
On his defeat to Alcaraz, he added: “It’s more difficult to understand the game. He breaks a lot of your rhythm. From the beginning I was not serving well. He was returning good, the second serves. He got more used to it on court. In the beginning, there was a bit more pressure, same as me. But yeah, he got an early break in the beginning of the 1st set as well 2nd set. Then he played his game. With good shots, going to the net, approaching. I think the Jannik game helped me to enter the court with no fear. Trying to play my game. But I think I didn’t get the opportunities that I had. And of course he played good. He’s No 1 in the world. I need to think about my mistakes and trying to improve.”
Fonseca’s comparison of Sinner to a robot underlines the Italian’s consistency and precision, though Sinner himself has acknowledged the need to become less predictable—particularly against the dynamic Alcaraz.
After losing the US Open final 2025 to Alcaraz, Sinner said: “I was very predictable today on court. He did many things, he changed up the game. That’s also his style of how he plays. Now it’s going to be on me if I want to make changes or not.
“That’s definitely [what] we are going to work on. I’m trying to be more prepared for the next match that I will play against him.
“It also depends on how you arrive to play against Carlos. One thing is when the scoreline [or] matches before are comfortable but you always do the same things, like I did, for example, during this tournament, I didn’t make one serve-volley, didn’t use a lot of drop shots, and then you arrive to a point where you play against Carlos where you have to go out of the comfort zone.
“So I’m going to aim to maybe even lose some matches from now on, but trying to do some changes, trying to be a bit more unpredictable as a player, because I think that’s what I have to do, trying to become a better tennis player. At the end of the day, that’s my main goal.”
For his part, Alcaraz praised Fonseca’s potential and highlighted the value of competing against top-ranked opponents. Drawing from his own experience of facing Rafael Nadal early in his career, he said:
“Well I do remember when I played Rafa Nadal for the first time in Madrid. I remember how good that match was for me, even though I was destroyed. I would say for him playing toe to toe with us, he and his team are going get great feedback and know what he should improve in the future. He has everything. Great shots. A lot of things to improve. But I’m pretty sure he’s gonna do it. Back-to-back tournaments playing against No 1 and No 2 in the world is gonna be really helpful for him.”
