Gilles Simon holds a solid career record of 504–394 across 898 matches (56.1%). A winning majority across 898 matches shows consistent ability to get results on Tour. With 14 titles, among the most prolific champions in the Open Era: Marseille, Bucharest, Casablanca, Indianapolis and 5 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 90–61 (59.6%) across 151 matches — a player who generally rises to the occasion at the Slams.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): a positive 124–109 (53.2%) across 233 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
22 finals reached — won 14, lost 8 (solid 64% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 51 semifinals. 100 quarterfinals.
vs. Top 10: 34–94 (26.6%, 128 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: 95–70 (57.6%); best-of-three: 409–324 (55.8%). Consistent regardless of format — a sign of a well-rounded game that holds up as matches develop.
Dominant season: 2008 — 51–27 (65.4%) from 78 matches. That year represents a level of dominance that sets the ceiling for what Gilles Simon can produce.
