David Rikl has found clay courts difficult, recording 32–46 across 78 matches (41.0%). 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): David Rikl is 3–4 (42.9%) across 7 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): David Rikl is 5–6 (45.5%) across 11 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.

2 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. 6 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 1–5 (16.7%, 6 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: 3–4 (42.9%); best-of-three: 29–42 (40.8%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1992 — 5–4 (55.6%) from 9 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
