John Frawley has found clay courts difficult, recording 13–17 across 30 matches (43.3%). 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 (Roland Garros): John Frawley is 4–3 (57.1%) 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 clay — best-of-five: 4–3 (57.1%); best-of-three: 9–14 (39.1%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1984 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
