Gabriel Diallo has a competitive clay court record of 7–8 across 15 matches (46.7%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Roland Garros): 1–2 across just 3 matches — still very early days at this level on clay.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 4–3 (57.1%) across 7 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

By format on clay — best-of-five: 1–2 (33.3%); best-of-three: 6–6 (50.0%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 2025 — 6–4 (60.0%) from 10 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.

Recent Form 2026: 1–3 (25.0%) on clay. Last 4: L L W L — mixed results, some inconsistency in the current period.
