We looked at how old every current ATP top 100 player was when they turned professional. The average is 18 — but the gap between the earliest and latest entries is wider than most people expect.
We ran the numbers on every ATP ranked player's backhand grip using our own dataset. The one-hander is dying — but it hasn't been filtered out at the elite end, and the data behind that finding is more interesting than you'd expect.
We looked at the coaching data for every player in the ATP top 50. The father-son pattern is more common than you'd expect — and some of the world's best players are being guided by former Grand Slam champions.
We pulled the height of every player in the ATP top 100 from our database. The tallest is 211cm. The shortest is 170cm. And the relationship between height and ranking is more complicated than most people assume.
The current ATP top 100 spans 22 years of age — from a 19-year-old Brazilian to a 41-year-old Swiss. We looked at every player's date of birth and found a sport in genuine generational transition.
We mapped every ATP top 100 player back to their country and adjusted for population. The results completely flip the conventional table — and explain why small nations punch far above their weight in professional tennis.
