Stefan Simonsson has a competitive grass court record of 8–8 across 16 matches (50.0%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Wimbledon): Stefan Simonsson is 7–6 (53.8%) across 13 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: 7–6 (53.8%); best-of-three: 1–2 (33.3%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1984 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
