Robert Seguso has found clay courts difficult, recording 3–10 across 13 matches (23.1%). 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): Robert Seguso 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: 3–4 (42.9%); best-of-three: 0–6 (0.0%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1984 — 1–5 (16.7%) from 6 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
