Tom Okker has an impressive career record of 666–274 across 940 matches (70.9% — strong). A win rate of that calibre over 940 matches is a reliable indicator of genuine quality. With 35 titles, among the most prolific champions in the Open Era: Dublin, Kingston, Barranquilla, Johannesburg-1 and 27 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 73–29 (71.6%) across 102 matches — a player who generally rises to the occasion at the Slams.
65 finals reached — won 35, lost 30 (solid 54% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 115 semifinals. 171 quarterfinals.
vs. Top 10: 27–45 (37.5%, 72 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: 160–70 (69.6%); best-of-three: 504–203 (71.3%). Consistent regardless of format — a sign of a well-rounded game that holds up as matches develop.
Historic season: 1973 — 91–23 (79.8%) from 114 matches. A campaign of 91 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.
