Hans Simonsson has found clay courts difficult, recording 22–38 across 60 matches (36.7%). 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): Hans Simonsson 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.

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. 3 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 2–6 (25.0%, 8 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: 19–34 (35.8%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1982 — 6–5 (54.5%) from 11 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
