Federico Browne has found clay courts difficult, recording 9–14 across 23 matches (39.1%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Roland Garros): Federico Browne is 2–2 (50.0%) across 4 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on clay — best-of-five: 2–2 (50.0%); best-of-three: 7–12 (36.8%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 2000 — 4–5 (44.4%) from 9 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
