Clark Graebner has been dominant on grass, posting 115–31 across 146 matches (78.8% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career on grass. 5 titles on grass: Manchester, Beckenham, Southampton, Haverford, South Orange — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Wimbledon): a positive 31–13 (70.5%) across 44 matches — a player who generally rises to the occasion at the Slams on grass.

9 finals reached on grass — won 5, lost 4 (solid 56% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on grass. 19 semifinals. 23 quarterfinals.

By format on grass — best-of-five: 43–17 (71.7%); best-of-three: 72–14 (83.7%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on grass.

Peak season: 1971 — 26–5 (83.9%) from 31 matches. That year captures the ceiling of what Clark Graebner can do on grass when performing at their best and represents the standard to aim for.

Clark Graebner 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.
