Radek Stepanek holds a solid career record of 384–302 across 686 matches (56.0%). A winning majority across 686 matches shows consistent ability to get results on Tour. 5 titles: Rotterdam, Los Angeles, Brisbane, San Jose, Washington — a record that reflects consistent ability to close out tournaments.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Radek Stepanek is 58–55 (51.3%) across 113 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): a positive 96–88 (52.2%) across 184 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
14 finals reached — won 5, lost 9 (36% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 35 semifinals. 68 quarterfinals.
vs. Top 10: 24–80 (23.1%, 104 matches). Top 10 opponents have represented a clear ceiling; addressing that deficit is the single biggest lever for improving the overall record.
By format — best-of-five: 72–70 (50.7%); best-of-three: 312–232 (57.4%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Dominant season: 2009 — 47–21 (69.1%) from 68 matches. That year represents a level of dominance that sets the ceiling for what Radek Stepanek can produce.
