Nicolas Kiefer holds a solid career record of 366–274 across 640 matches (57.2%). A winning majority across 640 matches shows consistent ability to get results on Tour. 6 titles: Toulouse, Tokyo, Halle, Tashkent, Dubai, Hong Kong — a record that reflects consistent ability to close out tournaments.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Nicolas Kiefer is 60–44 (57.7%) across 104 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 87–83 (51.2%) across 170 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
21 finals reached — won 6, lost 15 (29% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 35 semifinals. 67 quarterfinals.
vs. Top 10: 35–74 (32.1%, 109 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: 66–55 (54.5%); best-of-three: 300–219 (57.8%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Dominant season: 1999 — 54–25 (68.4%) from 79 matches. That year represents a level of dominance that sets the ceiling for what Nicolas Kiefer can produce.
