Pascal Portes has found clay courts difficult, recording 34–51 across 85 matches (40.0%). 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): Pascal Portes is 8–8 (50.0%) across 16 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

5 quarterfinals on clay, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

vs. Top 10 on clay: 3–5 (37.5%, 8 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: 9–10 (47.4%); best-of-three: 25–41 (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: 1979 — 9–7 (56.3%) from 16 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
