Quentin Halys has found grass courts difficult, recording 8–10 across 18 matches (44.4%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Wimbledon): Quentin Halys is 5–4 (55.6%) across 9 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on grass — best-of-five: 5–4 (55.6%); best-of-three: 3–6 (33.3%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 2022 — 2–3 (40.0%) from 5 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
