Vladimir Zednik has found grass courts difficult, recording 13–19 across 32 matches (40.6%). 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): Vladimir Zednik is 8–10 (44.4%) across 18 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: 11–15 (42.3%); best-of-three: 2–4 (33.3%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1970 — 3–3 (50.0%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
