Robin Haase has found grass courts difficult, recording 22–34 across 56 matches (39.3%). 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): Robin Haase is 8–11 (42.1%) across 19 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on grass: 1–5 (16.7%, 6 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: 8–11 (42.1%); best-of-three: 14–23 (37.8%). Slightly better in five-set matches on grass — a positive sign for the Slams specifically.

Best season: 2015 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
