Russell Simpson has a competitive grass court record of 58–61 across 119 matches (48.7%). 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): Russell Simpson is 15–22 (40.5%) across 37 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 semifinals on grass without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 8 quarterfinals adds further depth to that picture.

vs. Top 10 on grass: 2–4 (33.3%, 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: 23–29 (44.2%); best-of-three: 35–32 (52.2%). 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: 1974 — 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.
