Dick Norman has found clay courts difficult, recording 6–15 across 21 matches (28.6%). 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): Dick Norman is 4–5 (44.4%) across 9 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: 4–5 (44.4%); best-of-three: 2–10 (16.7%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 2006 — 1–4 (20.0%) from 5 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
