Thanasi Kokkinakis has found clay courts difficult, recording 9–16 across 25 matches (36.0%). 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): Thanasi Kokkinakis is 6–5 (54.5%) across 11 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Thanasi Kokkinakis has struggled at Masters level on clay: 1–5 (16.7%) in 6 matches. Improving at this level is the clearest path to a stronger overall record on this surface.

vs. Top 10 on clay: 0–4 (0.0%, 4 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: 6–5 (54.5%); best-of-three: 3–11 (21.4%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 2023 — 3–3 (50.0%) from 6 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
