Gustavo Tiberti has found clay courts difficult, recording 11–25 across 36 matches (30.6%). 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): 1–2 across just 3 matches — still very early days at this level on clay.

vs. Top 10 on clay: 0–3 (0.0%, 3 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: 1–2 (33.3%); best-of-three: 10–23 (30.3%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1982 — 7–7 (50.0%) from 14 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
