Zoltan Kuharszky has found clay courts difficult, recording 27–41 across 68 matches (39.7%). 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): Zoltan Kuharszky has yet to record a win on clay at this stage — 0–3 across 3 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

7 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.

By format on clay — best-of-five: 0–3 (0.0%); best-of-three: 27–38 (41.5%). 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: 1984 — 10–9 (52.6%) from 19 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
