Jurgen Zopp has found clay courts difficult, recording 11–14 across 25 matches (44.0%). 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): Jurgen Zopp is 3–4 (42.9%) across 7 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: 7–9 (43.8%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Best season: 2018 — 5–4 (55.6%) from 9 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
