Maximilian Marterer has found grass courts difficult, recording 4–10 across 14 matches (28.6%). 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): Maximilian Marterer is 3–4 (42.9%) 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 grass — best-of-five: 3–4 (42.9%); best-of-three: 1–6 (14.3%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.
