Lukas Lacko has found grass courts difficult, recording 19–26 across 45 matches (42.2%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar. Lukas Lacko has reached 1 final without yet claiming a title on grass — one of the finest margins in tennis.

At Grand Slam level (Wimbledon): Lukas Lacko is 6–9 (40.0%) across 15 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

One final reached on grass, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 1 semifinal. 2 quarterfinals.

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: 6–9 (40.0%); best-of-three: 13–17 (43.3%). Slightly stronger in three-set contests on grass, though the five-set record is still respectable.

Best season: 2018 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
