Peter McNamara has found grass courts difficult, recording 24–32 across 56 matches (42.9%). 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): Peter McNamara is 19–18 (51.4%) across 37 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

4 quarterfinals on grass, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

vs. Top 10 on grass: 0–5 (0.0%, 5 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: 19–19 (50.0%); best-of-three: 5–13 (27.8%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1981 — 7–3 (70.0%) from 10 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
