Gaston Gaudio holds a solid career record of 271–196 across 467 matches (58.0%). A winning majority across 467 matches shows consistent ability to get results on Tour. 8 titles: Barcelona, Mallorca, Roland Garros, Vina del Mar, Buenos Aires, Estoril, Gstaad, Kitzbuhel — a record that reflects consistent ability to close out tournaments.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Gaston Gaudio is 36–31 (53.7%) across 67 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 62–60 (50.8%) across 122 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
17 finals reached — won 8, lost 9 (47% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 30 semifinals. 48 quarterfinals.
vs. Top 10: 12–33 (26.7%, 45 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: 46–39 (54.1%); best-of-three: 225–157 (58.9%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Dominant season: 2005 — 55–21 (72.4%) from 76 matches. That year represents a level of dominance that sets the ceiling for what Gaston Gaudio can produce.
