Antonio Munoz has found clay courts difficult, recording 96–137 across 233 matches (41.2%). 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): Antonio Munoz is 10–12 (45.5%) across 22 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

3 semifinals on clay without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 12 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 0–18 (0.0%, 18 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: 15–20 (42.9%); best-of-three: 81–117 (40.9%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Best season: 1969 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
