Nicolas Almagro has an impressive clay court record of 279–146 across 425 matches (65.6% — strong). A win rate of that calibre over 425 matches is a reliable indicator of genuine quality on this surface. With 13 titles, among the most prolific clay court champions in the Open Era: Valencia, Costa do Sauipe, Acapulco, Bastad and 5 more.

At Grand Slam level (Roland Garros): a positive 24–14 (63.2%) across 38 matches — a player who generally rises to the occasion at the Slams on clay.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 37–32 (53.6%) across 69 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

23 finals reached on clay — won 13, lost 10 (solid 57% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on clay. 39 semifinals. 64 quarterfinals.

vs. Top 10 on clay: 16–35 (31.4%, 51 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: 28–15 (65.1%); best-of-three: 251–131 (65.7%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Dominant season: 2012 — 35–9 (79.5%) from 44 matches. A campaign of 35 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.
