Felix Mantilla holds a solid career record of 313–218 across 531 matches (58.9%). A winning majority across 531 matches shows consistent ability to get results on Tour. With 10 titles, among the most prolific champions in the Open Era: Oporto, Bologna, Gstaad, Umag and 5 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Felix Mantilla is 35–34 (50.7%) across 69 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 53–49 (52.0%) across 102 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
22 finals reached — won 10, lost 12 (45% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 36 semifinals. 65 quarterfinals.
vs. Top 10: 14–32 (30.4%, 46 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: 39–36 (52.0%); best-of-three: 274–182 (60.1%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Dominant season: 1997 — 53–22 (70.7%) from 75 matches. That year represents a level of dominance that sets the ceiling for what Felix Mantilla can produce.
