Jose Higueras has an impressive clay court record of 392–183 across 575 matches (68.2% — strong). A win rate of that calibre over 575 matches is a reliable indicator of genuine quality on this surface. With 15 titles, among the most prolific clay court champions in the Open Era: Santiago, Murcia, Cairo, Nice and 9 more.

At Grand Slam level (Roland Garros): a positive 33–15 (68.8%) across 48 matches — a player who generally rises to the occasion at the Slams on clay.

27 finals reached on clay — won 15, lost 12 (solid 56% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on clay. 49 semifinals. 76 quarterfinals.

vs. Top 10 on clay: 23–49 (31.9%, 72 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: 48–32 (60.0%); best-of-three: 344–151 (69.5%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Dominant season: 1979 — 58–14 (80.6%) from 72 matches. A campaign of 58 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.
