Olivier Patience has found clay courts difficult, recording 19–34 across 53 matches (35.8%). 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): Olivier Patience is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on clay: 2–3 (40.0%, 5 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall clay court profile.

By format on clay — best-of-five: 4–6 (40.0%); best-of-three: 15–28 (34.9%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 2007 — 6–6 (50.0%) from 12 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
