Joao Fonseca is due to play Carlos Alcaraz at the Miami Open later today, in the first-ever competitive meeting of their careers.
It is a rivalry that some suggest could turn into one of tennis’ greatest, with the world number one certain to at least be troubled by this teenage superstar.
However, for all the excitement surrounding this upcoming clash, it might actually be a source of worry for tournament director James Blake.
That is, if what happened last year is anything to go by.
James Blake makes bold claim about Joao Fonseca’s popularity
Speaking to Andy Roddick on his Served podcast, he spoke about the Joao Fonseca factor and what it is like to deal with a player of his popularity.
“It’s unique,” he admitted. “Joao Fonseca, I learned last year, and I learned my lesson. He is one of one in Miami.”
What would have happened if Carlos Alcaraz and Jannik Sinner played at the same time as Roger Federer and Rafael Nadal?
Blake explained why, referencing some of tennis’ greatest-ever players in comparison including Roger Federer: “We have had great drawers here and great players in Roger, Rafa and Novak. All the great players. We have had Juan Martin Del Potro, who was extremely popular, but Joao Fonseca is different.
“I have never had a security warning from any of them and the way it was last year with him. That changed last year, that kind of excitement.”
The tournament director then went on to outline his expectations for this year, having already seen Fonseca perform well in his opening-round match.
Blake added: “We are going to find out just how much this has staying power [this year] and not just the tennis accomplishments because he would go on stadium before a lot of more accomplished players and people who have greater resumes and have done more in their careers, so that’s where you have to make that determination.
“Eala as well is a phenomenon. She has fans everywhere in the world now, so that means you have to readjust your assessment.
“I feel like I would when I first say when I first started this tournament that so and so has four Grand Slams and so and so has two Grand Slams, so the one with four Grand Slams is going on stadium and the one with two Grand Slams is going on Grandstand. It was on their tennis accomplishments.
“But with Fonseca that has changed a bit because of how popular he is here in Miami.
“I don’t speak for other tournaments because I don’t know if it’s the same when he’s in Rome or Shanghai but here in Miami he is one of one.”
This comes less than a week after Blake confirmed that Fonseca and Alex Eala would play on the bigger courts at Miami to accommodate their fans rather than justify their rankings.
Is the Joao Fonseca hype justified?
There is plenty of hype around Fonseca, likely amplified by the unrelenting support he receives wherever he goes.
However, this loyal and passionate following has perhaps over-inflated expectations for the 19-year-old, who could justifiably have crumbled under this pressure across the last year or so.
Joao Fonseca will be the man to unsettle Carlos Alcaraz and Jannik Sinner’s duopoly over men’s tennis – Prove us wrong!
Fortunately, it seems like Fonseca is made from tougher stuff.
Already a two-time champion on the ATP Tour, this inexperienced superstar made his debut in all four Grand Slam main draws last year and claimed a win in each event.
He also reached the third round at Roland Garros, Wimbledon and the US Open, two of which came at the age of 18.
Fonseca may not be winning major titles or rewriting the history books like Alcaraz, but his progress has been meteoric. It will be really interesting to see where he stands at the end of 2026, and whether he has taken that next step to further justify the hype.
