Belus Prajoux has found grass courts difficult, recording 3–8 across 11 matches (27.3%). 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): Belus Prajoux has yet to record a win on grass at this stage — 0–5 across 5 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

By format on grass — best-of-five: 0–5 (0.0%); best-of-three: 3–3 (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 grass.

Best season: 1978 — 3–3 (50.0%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
