Milan Holecek has a competitive grass court record of 20–21 across 41 matches (48.8%). 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): Milan Holecek is 9–13 (40.9%) across 22 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on grass — best-of-five: 9–14 (39.1%); best-of-three: 11–7 (61.1%). 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: 1971 — 7–5 (58.3%) from 12 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
