Jose Clavet has found clay courts difficult, recording 6–11 across 17 matches (35.3%). 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): 2–1 across just 3 matches — still very early days at this level on clay.

By format on clay — best-of-five: 2–1 (66.7%); best-of-three: 4–10 (28.6%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1989 — 2–4 (33.3%) from 6 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
