Raemon Sluiter has found clay courts difficult, recording 24–38 across 62 matches (38.7%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar. Raemon Sluiter has reached 2 finals without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Raemon Sluiter is 4–6 (40.0%) across 10 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): Raemon Sluiter has struggled at Masters level on clay: 1–3 (25.0%) in 4 matches. Improving at this level is the clearest path to a stronger overall record on this surface.

2 finals reached on clay — none converted into a title yet. Reaching 2 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 2 semifinals. 3 quarterfinals.

vs. Top 10 on clay: 0–5 (0.0%, 5 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: 4–9 (30.8%); best-of-three: 20–29 (40.8%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 2000 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
