At Grand Slam level (Wimbledon): Jonathan Stark is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

One final reached on grass, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 2 semifinals. 3 quarterfinals.

vs. Top 10 on grass: 1–6 (14.3%, 7 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: 4–6 (40.0%); best-of-three: 17–16 (51.5%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.

Best season: 1992 — 6–3 (66.7%) from 9 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
