Carlos Moya has an impressive clay court record of 337–143 across 480 matches (70.2% — strong). A win rate of that calibre over 480 matches is a reliable indicator of genuine quality on this surface. With 16 titles, among the most prolific clay court champions in the Open Era: Buenos Aires, Umag, Monte Carlo Masters, Roland Garros and 5 more.

At Grand Slam level (Roland Garros): Carlos Moya has been outstanding — 32–12 (72.7%) across 44 matches. Winning more than 7 in 10 Grand Slam matches on clay is the benchmark of an all-time great on this surface.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 63–37 (63.0%) across 100 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

28 finals reached on clay — won 16, lost 12 (solid 57% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on clay. 52 semifinals. 74 quarterfinals.

vs. Top 10 on clay: 18–25 (41.9%, 43 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall clay court profile.

By format on clay — best-of-five: 49–18 (73.1%); best-of-three: 288–125 (69.7%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Dominant season: 2002 — 34–7 (82.9%) from 41 matches. A campaign of 34 wins on clay in a single season is among the best single-season records the surface has seen — the clearest benchmark of what is achievable at peak level.
