David Rikl has found grass courts difficult, recording 2–8 across 10 matches (20.0%). 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): David Rikl is 2–3 (40.0%) across 5 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on grass — best-of-five: 2–4 (33.3%); best-of-three: 0–4 (0.0%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1997 — 2–3 (40.0%) from 5 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
