Erik Van Dillen has a competitive clay court record of 44–50 across 94 matches (46.8%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Roland Garros): Erik Van Dillen is 9–9 (50.0%) across 18 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

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: 3–10 (23.1%); best-of-three: 41–40 (50.6%). 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: 1969 — 5–2 (71.4%) from 7 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
