Norbert Gombos has found clay courts difficult, recording 13–18 across 31 matches (41.9%). 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): Norbert Gombos is 2–3 (40.0%) across 5 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

4 quarterfinals on clay — 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: 2–4 (33.3%); best-of-three: 11–14 (44.0%). 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: 2021 — 7–5 (58.3%) from 12 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
