Adrian Ungur has found clay courts difficult, recording 11–26 across 37 matches (29.7%). 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): 1–2 across just 3 matches — still very early days at this level on clay.

vs. Top 10 on clay: 0–3 (0.0%, 3 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: 3–7 (30.0%); best-of-three: 8–19 (29.6%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Best season: 2010 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
