Jiri Novak has a competitive grass court record of 17–17 across 34 matches (50.0%). 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): Jiri Novak is 8–11 (42.1%) across 19 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: 8–11 (42.1%); best-of-three: 9–6 (60.0%). 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: 2003 — 6–3 (66.7%) from 9 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
