Jiri Vanek has found grass courts difficult, recording 1–7 across 8 matches (12.5%). 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): Jiri Vanek 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: 1–2 (33.3%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.
