Lars Burgsmuller has found clay courts difficult, recording 20–44 across 64 matches (31.3%). 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): Lars Burgsmuller is 4–5 (44.4%) across 9 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): Lars Burgsmuller has struggled at Masters level on clay: 3–6 (33.3%) in 9 matches. Improving at this level is the clearest path to a stronger overall record on this surface.

vs. Top 10 on clay: 2–5 (28.6%, 7 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: 4–6 (40.0%); best-of-three: 16–38 (29.6%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 2001 — 4–5 (44.4%) from 9 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
