A win rate of that calibre over 320 matches is a reliable indicator of genuine quality on this surface. 8 titles on clay: Mallorca, Vina del Mar, Buenos Aires, Estoril, Gstaad, Barcelona, Kitzbuhel, Roland Garros — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Roland Garros): a positive 21–9 (70.0%) across 30 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 32–23 (58.2%) across 55 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

17 finals reached on clay — won 8, lost 9 (47% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 28 semifinals. 41 quarterfinals.

vs. Top 10 on clay: 7–19 (26.9%, 26 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: 31–16 (66.0%); best-of-three: 180–93 (65.9%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.
