Karol Kucera has a competitive career record of 293–244 across 537 matches (54.6%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. 6 titles: Rosmalen, Ostrava, Sydney Outdoor, New Haven, Basel, Copenhagen — a record that reflects consistent ability to close out tournaments.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Karol Kucera is 41–41 (50.0%) across 82 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): Karol Kucera is 31–42 (42.5%) across 73 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the calendar.
13 finals reached — won 6, lost 7 (46% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 27 semifinals. 55 quarterfinals.
vs. Top 10: 28–41 (40.6%, 69 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall career profile.
By format — best-of-five: 62–54 (53.4%); best-of-three: 231–190 (54.9%). Consistent regardless of format — a sign of a well-rounded game that holds up as matches develop.
Dominant season: 1998 — 53–29 (64.6%) from 82 matches. That year represents a level of dominance that sets the ceiling for what Karol Kucera can produce.
