Peter Jackson has found grass courts difficult, recording 4–8 across 12 matches (33.3%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

By format on grass — best-of-five: 0–4 (0.0%); best-of-three: 4–4 (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.
