John Frawley has found grass courts difficult, recording 12–21 across 33 matches (36.4%). 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 Frawley is 5–7 (41.7%) across 12 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: 0–3 (0.0%, 3 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: 5–7 (41.7%); best-of-three: 7–14 (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: 1987 — 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.
