At Grand Slam level (Wimbledon): Geoff Masters is 22–25 (46.8%) across 47 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 finals reached on grass — won 1, lost 1 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on grass. 4 semifinals. 12 quarterfinals.

vs. Top 10 on grass: 0–5 (0.0%, 5 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.
