Drew Gitlin has found grass courts difficult, recording 10–13 across 23 matches (43.5%). 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): Drew Gitlin is 8–6 (57.1%) across 14 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: 6–6 (50.0%); best-of-three: 4–7 (36.4%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1982 — 5–4 (55.6%) from 9 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
