Thierry Tulasne holds a solid clay court record of 175–137 across 312 matches (56.1%).

At Grand Slam level (Roland Garros): Thierry Tulasne is 16–12 (57.1%) across 28 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

9 finals reached on clay — won 4, lost 5 (44% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 12 semifinals. 34 quarterfinals.

vs. Top 10 on clay: 8–24 (25.0%, 32 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: 23–19 (54.8%); best-of-three: 152–118 (56.3%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Peak season: 1985 — 29–12 (70.7%) from 41 matches. That year captures the ceiling of what Thierry Tulasne can do on clay when performing at their best and represents the standard to aim for.
