Wayne Black 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): Wayne Black is 3–4 (42.9%) across 7 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: 4–5 (44.4%); best-of-three: 3–7 (30.0%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1998 — 4–4 (50.0%) from 8 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
