Grega Zemlja has a competitive grass court record of 8–7 across 15 matches (53.3%). 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): Grega Zemlja is 4–4 (50.0%) across 8 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

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: 5–4 (55.6%); best-of-three: 3–3 (50.0%). Slightly better in five-set matches on grass — a positive sign for the Slams specifically.

Best season: 2013 — 4–3 (57.1%) from 7 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
