Martin Wostenholme has found clay courts difficult, recording 28–43 across 71 matches (39.4%). 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.

vs. Top 10 on clay: 1–5 (16.7%, 6 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 6–7 (46.2%); best-of-three: 22–36 (37.9%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1987 — 4–4 (50.0%) from 8 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
