At Grand Slam level (Roland Garros): Eric Winogradsky is 5–6 (45.5%) across 11 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on clay: 1–2 (33.3%, 3 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: 5–6 (45.5%); best-of-three: 2–5 (28.6%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.
