Yannick Hanfmann has found grass courts difficult, recording 7–12 across 19 matches (36.8%). 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): Yannick Hanfmann has yet to record a win on grass at this stage — 0–3 across 3 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

vs. Top 10 on grass: 1–4 (20.0%, 5 matches). Top 10 opponents have represented a clear ceiling on grass; addressing that deficit is the single biggest lever for improving the overall record here.

By format on grass — best-of-five: 0–3 (0.0%); best-of-three: 7–9 (43.8%). 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: 2023 — 4–3 (57.1%) from 7 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
