Magnus Gustafsson has an impressive clay court record of 213–114 across 327 matches (65.1% — strong). A win rate of that calibre over 327 matches is a reliable indicator of genuine quality on this surface. 8 titles on clay: Bastad, Munich, Amsterdam, Hilversum, Stuttgart Outdoor — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Roland Garros): Magnus Gustafsson is 14–13 (51.9%) across 27 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 31–20 (60.8%) across 51 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. 27 semifinals. 44 quarterfinals.

vs. Top 10 on clay: 8–8 (50.0%, 16 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: 21–22 (48.8%); best-of-three: 192–92 (67.6%). 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: 1991 — 41–8 (83.7%) from 49 matches. A campaign of 41 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.
