Clay Court Statistics Overview
Willem Prinsloo has found clay courts difficult, recording 4–16 across 20 matches (20.0%). 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): 1–2 across just 3 matches — still very early days at this level on clay.
Best season: 1977 — 3–12 (20.0%) from 15 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
