Clark Graebner has an impressive career record of 348–156 across 504 matches (69.0% — strong). A win rate of that calibre over 504 matches is a reliable indicator of genuine quality. With 13 titles, among the most prolific champions in the Open Era: Sacramento, Milwaukee, Richmond, Buffalo and 8 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 33–15 (68.8%) across 48 matches — a player who generally rises to the occasion at the Slams.
30 finals reached — won 13, lost 17 (43% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 65 semifinals. 92 quarterfinals.
By format — best-of-five: 79–38 (67.5%); best-of-three: 268–115 (70.0%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Historic season: 1968 — 77–20 (79.4%) from 97 matches. A campaign of 77 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.
