Jakob Hlasek has a competitive grass court record of 36–34 across 70 matches (51.4%). 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): Jakob Hlasek is 23–17 (57.5%) across 40 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 semifinals on grass without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 3 quarterfinals adds further depth to that picture.

vs. Top 10 on grass: 1–4 (20.0%, 5 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: 23–20 (53.5%); best-of-three: 13–14 (48.1%). Slightly better in five-set matches on grass — a positive sign for the Slams specifically.

Best season: 1991 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
