Cliff Richey has an impressive career record of 488–223 across 711 matches (68.6% — strong). A win rate of that calibre over 711 matches is a reliable indicator of genuine quality. With 23 titles, among the most prolific champions in the Open Era: Curacao, Salisbury, Houston-2, New Orleans-2 and 18 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 45–20 (69.2%) across 65 matches — a player who generally rises to the occasion at the Slams.
41 finals reached — won 23, lost 18 (solid 56% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 72 semifinals. 126 quarterfinals.
vs. Top 10: 5–22 (18.5%, 27 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: 95–38 (71.4%); best-of-three: 392–182 (68.3%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Historic season: 1970 — 83–24 (77.6%) from 107 matches. A campaign of 83 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.
