David Lloyd has found clay courts difficult, recording 10–29 across 39 matches (25.6%). 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 (Roland Garros): David Lloyd has yet to record a win on clay at this stage — 0–6 across 6 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

By format on clay — best-of-five: 2–15 (11.8%); best-of-three: 8–14 (36.4%). 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: 1968 — 3–3 (50.0%) from 6 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
