Jarkko Nieminen has found grass courts difficult, recording 25–32 across 57 matches (43.9%). 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): Jarkko Nieminen is 14–12 (53.8%) across 26 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: 0–6 (0.0%, 6 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: 14–12 (53.8%); best-of-three: 11–20 (35.5%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 2006 — 5–2 (71.4%) from 7 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
