The brief

Every parent asks it.
Where did they train?

My wife, our daughter and I all play. Choosing where a kid should train is guesswork: every academy says it made champions, and nobody shows the list.

So I checked. Every ranked ATP and WTA player, one by one: where they grew up, which club or academy, and what training there costs today, wherever the place publishes its prices.

The work

3,853 players.
1,207 traced.
One product.

Research first, then design, then the build — every page made from the data, nothing typed by hand.

01

Research

Every ranked player checked against club, academy and federation records.

02

Design

One page per place: the pros who grew up there, the programmes, real prices in dollars.

03

Always fresh

The rankings refresh every week; a question to an academy goes through one simple form.

Why I built it
I built Baseline for families like mine. It is also the proof of what I build for clubs and academies: real data, every page complete, fast on a phone at the courts.
