Alcaraz-Fonseca-Sinner: A quick stat glance at the potential next big 3.

Rovesciarete

Hall of Fame
Some rough comparison of the current state of Fonsinneraz + old Djokovic. Joao is like Novak obviously handicapped by his age - maybe I will post some age-adjusted stuff - but his game already stacks up surprisingly well.

In some ways we have in "rally" a Carlos-Joao and Novak-Jannik pairing. The former try to end the point a lot quicker, especially Fonseca is rocketing returns. Fits his perceived lack of stamina and his definite possession of a huger forehand. Both also get less help from the serve which depresses their 1-3 rally length win rate.

Novak and Sinner built the points more carefully and go for more efficiency from the baseline, aided by their superior backhand but also profit from a better serve to dominate the key 1-3 point rallies.

All four are excellent at winning long rallies as well, with Alcaraz doing fantastic and Sinner winning a bonkers almost 58% of the 10+ rallies!

In 'tactics' things change and old Novak and young Carlos employ serve and volley almost thrice as often. They go to the net also much more frequently and the difference is arguably greater than the stats suggest, as we have a baseline of 'given', easy net points. This helps to partly explain the very high efficiency of Sinner at the net. Fonseca should improve here over the years.

Joao and Carlos have higher win percentages for their groundstroke as they are more aggressive and lack the big serve. Here the difference between those categories are more interesting:

Rovescio, start a substack. This is way too well thought out to be confined to an obscure tennis forum.

Thanks for the flowers, but that would entail more investment on my part. Stat sheets tent to be try and you need great writing skills to put a little bit of excitement into them.

Really like how Fonseca mostly uses his slices on clay. It can fulfill an important tactical role, more so for a guy with a great, but flattish two-handed backhand.* Reminds me of Alcaraz and even a bit of Nadal, despite the challenges being different for a lefty. Sinner may have a worse slice, but incurs generally higher opportunity cost, as he can shape the ball more due to his active left arm.

*A one-hander needs the slice more to defend against a high bouncing ball. Federer often managed to break the sidelines due to being Roger and getting forward.
 
The 2025 matches have not been charted at all so these numbers are from last year as far as we know.

Fonseca would likely be even more dominant by now. He is truly top 10 worthy right now even though just 18. But the physical stuff will probably take a year or two. The game he can play is able to beat almost every single player even now.

Great notes. Among others I find BH efficacy/resilience separates the four. Sinner / Nole can shape the ball better and with margin from the left and this, in combination with their dynamism, allow them to develop more consistent and effective baseline game.
 
One thing I found interesting on Joao's (early) stats: While he plays, relatively, the most short points, his win percentage improves on longer rallies.

Not sure exactly what that indicates, but maybe, that he has both quick-strike ability, and the ability to do quite well in the longer rallies. Seems like a good thing, and perhaps, all these numbers will improve as he comes of age.
 
Great thread OP! Fonseca is the next great young player. Fundamentally sound. He won't be a flash in the pan. Having said that I am interested to see how far Shapo's improved game takes him this year. Those of you who lament the demise of the big 3 aren't very forward-looking. When there is more parity among the top 10 players (each has an increased chance to win any grand slam), this makes it much more exciting than watching one of the big 3 (sorry Sir Andy) win all the time. Hey, that's just me. Pass me some popcorn! :)

That's very interesting, good post. A little counterintuitive as I think his movement is the biggest concern. Thanks for posting that
 
@Rovesciarete this is, potentially, excellent thread as this "big three" may kick in this or next year.

The Big 3 is Sinner, Djokovic and Carlos, in that order.
The thread's for future considerations. How many more years, or shall I say months, has Novak left in his tank?

The 2025 matches have not been charted at all so these numbers are from last year as far as we know.

Fonseca would likely be even more dominant by now. He is truly top 10 worthy right now even though just 18. But the physical stuff will probably take a year or two. The game he can play is able to beat almost every single player even now.
Great point as Joao is improving around the clock.

The new "Big Three" is on as long as Jannick doesn't succumb to illegal substances.

I will try to address most of the comments, but this will take some time. Some time ago, I compared the best young players and noticed a big divergence in trends of win percentage according to rally length. Even earlier, Sinneraz stood out for having both that nice upward slope, winning more and more as the rally goes longer and longer.

For me, this was a sign of 'pure' tennis game quality, as the impact of the serve gets neutralized. Sackmann has only recently written a great article about rally resilience, as he calls it, which I will discuss later.

However, in modern tennis, the serve plus is becoming ever better and more important, and most of the points are won there. So, ideally, a tennis player is able to convert advantages quickly and efficiently but is also able to resist to get 'another shot' to win the point. The degree of this quality sets Sinner, Alcaraz, and Djokovic certainly also apart from the rest.

FAA and De Minaur illustrate those usually conflicting poles of tennis. One embodies the serve plus, the other the rally resilience. One suffers from his poor backhand and outdoor movement, the other from his weak serve and lack of weapons. Some ATG can fuse those poles, and Fonseca seems to be on the right path.
 
Maybe i will update this thread in some time, I just wanted to say that I really liked Fonseca's grass season. At his age he is ahead of the fitness curve compared to Sinner, but there is still so much room to grow for his movement.

Love his ability to chop and slice from both wings, which he had to do quite often as he wasn't quick enough to drive some balls. Mensik had more success and I adore his serve, however problems areas like RoS ought to be harder to improve.

Fonseca is a star and he plays big. It would be very good for tennis if he happens, but right now there's nothing really that says it will.

Of course for now there is a big big gap between him and Sincaraz. However across all the surfaces he seems to me to have the best chance among the <21 to develop into an ATG.

Mensik has with his serve a mighty strength but his ground strokes are still somewhat underwhelming.
 
I was looking at the late 2022 numbers of Sincaraz to get a better gauge of Fonseca. Note that both became better as the rallies got longer and were very close to the top!*

Alcaraz suffered from his weak serve back in those days, Sinner was fairly balance even back then. Great baseline potency by both for their age!

2025 with Fonseca. Strange dip in the 7-9% range but if think this will trend up again, especially considering his 10+ W%. Great forehand and backhand numbers by Joao!

It’s far too early for Fonseca to deserve a place in any so-called Holy Trinity. We won’t have a new one as long as Djokovic remains the real third-best player on tour—also known as The Third Wheel, a title he’s recently stolen from Federer.

At their age we have some stat inflation for playing challenger, this goes for example for Basavareddy. Use Fils, Rune, Musetti etc. as gauges!

Some numbers are truly shocking, for example how few points Ben or Jiri win in longer rallies, not much better than Perribot. On the other hand Rune and Michelsen are very poor in the most common length of 1-3%.

Musetti might have one of the best one-hander of the last two decades! Draper has a strong backhand for a lefty. Mensik has a fantastic serve but poor baseline potency. Fonseca seems to be a sweet spot with few weaknesses and great strengths.

Fonseca being better in the 1-3 rallies then Shelton/ Perricard is great considering how much better their serves are compared to his
 
That's one of the most idiotic things I ever read here
there's a lot more on here.
However, Stan and Fed just were just alerted and hopped on a jet to take care of this misguided error in judgement about Musetti as best one-hander in the last 20 years.
 
After watching matches I enjoy confronting the eye test with hard data. Novak against Sincaraz was always a fruitful field, let us now throw young Fonseca into the mix.

1) Sinner is absurdly good in the longest rallies, 60%+ win rate with such a sample size is crazy. Of course he is also incredible in all the other parameters, be it forehands, backhands, etc, bar the use of the bh slice…

2) Alcaraz is fantastic in shortening and winning rallies but also at winning the longer ones. His backhand has improved markedly over the years, making him a much tougher opponent.

3) Novak is still a great first striker with brilliant power from both wings, but suffers increasingly in longer rallies. I can’t remember the last time I have seen him under 50% in a rally category.

4) Fonseca has already huge forehand power and a surprisingly strong serve. His relative return weakness is imho the biggest long time worry. Better legs will help, but he is far away from the prowess shown by Sincaraz and Novak in their youth.

Maybe I might add the raw data, but I like to distill the essence. So far I heard nothing to very little from knowledgeable people about the unique ability of Sinner to dominate long rallies or Fonseca’s return troubles.
