Joao Fonseca can be proud of another strong Grand Slam run, having just reached the third round of the French Open.
Fonseca has impressed Coco Gauff, with the former’s most recent exploits involving another huge Grand Slam upset.
Just 18, the Brazilian knocked 30th seed Hubert Hurkacz out of the French Open in the first round, winning their match 6-2, 6-4, 6-2.
Fonseca also defeated Pierre-Hugues Herbert in straight sets before falling to Jack Draper in the third round.
He currently occupies a career-high ranking of world number 57, and won his maiden ATP title in Buenos Aires earlier this year.
Sam Querrey and Jack Sock disagree over Joao Fonseca Grand Slam title chances
Teenage ace Fonseca may challenge Jannik Sinner and Carlos Alcaraz over the coming years, although he does still have some way to go to reach their level.
And his chances of future Grand Slam success have now been rated by a quartet of former players on the Nothing Major Show.
Discussing how many Grand Slam titles Fonseca can win, Sam Querrey said: “I’m going to say four. I mean he has got to deal with Sinner and Alcaraz for like 80% of his career.”
Steve Johnson commented: “I had him at five. I think he just hits the ball huge. He is going to get hot sometimes and hit the ball through these guys.”
John Isner then added: “I like your answer Stevie. I’ll go with five,” with Jack Sock saying: “I am going to say zero, one or two.”
Joao Fonseca ATP career stats after French Open third round run
It is certainly sensible to perhaps focus on another lower level ATP Tour title for Fonseca as opposed to Grand Slam success.
Achieving the former is hard enough, with so much skill and physical and mental strength needed to win the latter.
And throwing Sinner and Alcaraz into the mix simply makes the task much more difficult, with the pair having dominated the recent Grand Slams.
They account for each of the last six titles and seven of the last eight, with only veteran Novak Djokovic able to break that trend.
Fonseca would be wise to take each competition as they come, with plenty of success certain to go his way in the near future.
But toppling Sinner and Alcaraz will be a very difficult feat, although the Brazilian is arguably among a small group of players who look like being capable of doing exactly that.
| Rank | Win-loss | Titles | Prize money | |
| 2025 | 57 | 12-8 | 1 | $662,592 |
| Career | 57 (High) | 23-16 | 1 | $1,481,298 |
He will, however, very likely have to start winning Grand Slams sooner rather than later in order to keep tabs on the pair.
At 22, Alcaraz already has a remarkable five Grand Slam titles to his name, with 23-year-old Sinner on three.
