Bernard Mignot has found clay courts difficult, recording 27–43 across 70 matches (38.6%). 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): Bernard Mignot is 5–6 (45.5%) across 11 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: 10–12 (45.5%); best-of-three: 17–31 (35.4%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1973 — 8–6 (57.1%) from 14 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
