Quentin Halys has a competitive grass court record of 10–12 across 22 matches (45.5%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Wimbledon): Quentin Halys is 6–5 (54.5%) across 11 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: 6–5 (54.5%); best-of-three: 4–7 (36.4%). 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.

Recent Form 2026: 2–3 (40.0%) on grass. Last 5: L W L W L — mixed results, some inconsistency in the current period.
