Marian Vajda has a competitive clay court record of 94–87 across 181 matches (51.9%). The record shows a player capable of competing here, though there is clear room to push the win rate higher. Claimed 2 titles on clay: Prague, Geneva.

At Grand Slam level (Roland Garros): Marian Vajda is 6–9 (40.0%) across 15 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): Marian Vajda has struggled at Masters level on clay: 1–3 (25.0%) in 4 matches. Improving at this level is the clearest path to a stronger overall record on this surface.

4 finals reached on clay — won 2, lost 2 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on clay. 8 semifinals. 20 quarterfinals.

vs. Top 10 on clay: 5–6 (45.5%, 11 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: 6–10 (37.5%); best-of-three: 88–77 (53.3%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Peak season: 1987 — 23–9 (71.9%) from 32 matches. That year captures the ceiling of what Marian Vajda can do on clay when performing at their best and represents the standard to aim for.
