Ken Rosewall has been dominant on grass, posting 145–39 across 184 matches (78.8% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career on grass. 8 titles on grass: Bristol, Eastbourne, Newport-1, US Open, Australian Open, Newport, Brisbane — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Wimbledon): Ken Rosewall has been outstanding — 77–17 (81.9%) across 94 matches. Winning more than 7 in 10 Grand Slam matches on grass is the benchmark of an all-time great on this surface.

14 finals reached on grass — won 8, lost 6 (solid 57% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on grass. 24 semifinals. 31 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: 95–25 (79.2%); best-of-three: 50–14 (78.1%). Consistent regardless of format on grass — a sign of a well-rounded game that holds up as matches develop.

Best season: 1972 — 11–1 (91.7%) from 12 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.

Ken Rosewall assembled a remarkable 16-match winning streak on grass — a run of that length goes far beyond form and into a different level of dominance on this surface.
