At Grand Slam level (Wimbledon): Tim Wilkison is 15–21 (41.7%) across 36 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

5 finals reached on grass — won 2, lost 3 (40% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 7 semifinals. 12 quarterfinals.

vs. Top 10 on grass: 3–4 (42.9%, 7 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall grass court profile.

By format on grass — best-of-five: 19–21 (47.5%); best-of-three: 51–39 (56.7%). 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: 1978 — 8–3 (72.7%) from 11 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
