John Millman has found grass courts difficult, recording 13–18 across 31 matches (41.9%). 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): John Millman is 6–7 (46.2%) across 13 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: 0–4 (0.0%, 4 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: 6–7 (46.2%); best-of-three: 7–11 (38.9%). Slightly better in five-set matches on grass — a positive sign for the Slams specifically.

Best season: 2016 — 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.
