Martin Wostenholme has found grass courts difficult, recording 3–4 across 7 matches (42.9%). 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): 1–2 across just 3 matches — still very early days at this level on grass.

By format on grass — best-of-five: 1–2 (33.3%); best-of-three: 2–2 (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.
