Miloslav Mecir Sr. has an impressive career record of 262–122 across 384 matches (68.2% — strong). A win rate of that calibre over 384 matches is a reliable indicator of genuine quality. With 11 titles, among the most prolific champions in the Open Era: Rotterdam, Hamburg, Kitzbuhel, Auckland and 7 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 50–23 (68.5%) across 73 matches — a player who generally rises to the occasion at the Slams.
26 finals reached — won 11, lost 15 (42% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 33 semifinals. 54 quarterfinals.
vs. Top 10: 24–33 (42.1%, 57 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall career profile.
By format — best-of-five: 89–34 (72.4%); best-of-three: 173–88 (66.3%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Historic season: 1987 — 74–20 (78.7%) from 94 matches. A campaign of 74 wins in a single season is among the finest single-season records the Open Era has seen — the clearest benchmark of what is achievable at peak level.
