Paul Haarhuis has a competitive clay court record of 64–76 across 140 matches (45.7%). 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): Paul Haarhuis is 13–11 (54.2%) across 24 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): Paul Haarhuis is 20–25 (44.4%) across 45 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.

8 quarterfinals on clay, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

vs. Top 10 on clay: 6–12 (33.3%, 18 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: 18–14 (56.3%); best-of-three: 46–62 (42.6%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1993 — 13–8 (61.9%) from 21 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
