Paul-Henri Mathieu has found grass courts difficult, recording 22–31 across 53 matches (41.5%). 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): Paul-Henri Mathieu is 11–12 (47.8%) across 23 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on grass: 0–4 (0.0%, 4 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: 11–12 (47.8%); best-of-three: 11–19 (36.7%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 2007 — 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.
