Mario Ancic holds a solid career record of 208–135 across 343 matches (60.6%). A winning majority across 343 matches shows consistent ability to get results on Tour. Claimed 3 titles: 's-Hertogenbosch, St. Petersburg.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 43–21 (67.2%) across 64 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 39–36 (52.0%) across 75 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
11 finals reached — won 3, lost 8 (27% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 19 semifinals. 35 quarterfinals.
vs. Top 10: 13–41 (24.1%, 54 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: 51–31 (62.2%); best-of-three: 157–104 (60.2%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Dominant season: 2006 — 55–18 (75.3%) from 73 matches. That year represents a level of dominance that sets the ceiling for what Mario Ancic can produce.
