Carlos Costa has a competitive career record of 248–208 across 456 matches (54.4%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. 6 titles: Buenos Aires, Estoril, San Marino, Barcelona, Hilversum — a record that reflects consistent ability to close out tournaments.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Carlos Costa is 25–25 (50.0%) across 50 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 41–38 (51.9%) across 79 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
14 finals reached — won 6, lost 8 (43% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 23 semifinals. 47 quarterfinals.
vs. Top 10: 11–24 (31.4%, 35 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: 31–31 (50.0%); best-of-three: 217–177 (55.1%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Dominant season: 1993 — 45–26 (63.4%) from 71 matches. That year represents a level of dominance that sets the ceiling for what Carlos Costa can produce.
