Jan Kukal has found the Tour difficult, recording 58–79 across 137 matches (42.3%). The numbers point to a player still building their Tour presence — a key area of opportunity going forward.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Jan Kukal is 10–14 (41.7%) across 24 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
By format — best-of-five: 22–28 (44.0%); best-of-three: 36–51 (41.4%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Best season: 1969 — 15–13 (53.6%) from 28 matches. The best single-season display to date — a useful reference point as the career continues to develop.
