Gene Mayer has a competitive grass court record of 15–13 across 28 matches (53.6%). 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): a positive 12–7 (63.2%) across 19 matches — a player who generally rises to the occasion at the Slams on grass.

vs. Top 10 on grass: 0–3 (0.0%, 3 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: 12–7 (63.2%); best-of-three: 3–6 (33.3%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 1980 — 4–1 (80.0%) from 5 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
