Jean-Francois Caujolle has reached 1 final without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Jean-Francois Caujolle is 11–11 (50.0%) across 22 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

One final reached on clay, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 5 semifinals. 10 quarterfinals.

vs. Top 10 on clay: 3–9 (25.0%, 12 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: 9–8 (52.9%); best-of-three: 57–73 (43.8%). 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.
