Alex Lopez Moron has found clay courts difficult, recording 18–31 across 49 matches (36.7%). 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.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 2–2 (50.0%) across 4 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

By format on clay — best-of-five: 1–2 (33.3%); best-of-three: 17–29 (37.0%). Slightly stronger in three-set contests on clay, though the five-set record is still respectable.

Best season: 1995 — 11–13 (45.8%) from 24 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
