Francisco Gonzalez has found grass courts difficult, recording 17–27 across 44 matches (38.6%). 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): Francisco Gonzalez is 10–9 (52.6%) across 19 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: 11–11 (50.0%); best-of-three: 6–16 (27.3%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1981 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
