Ken Rosewall has an impressive career record of 546–192 across 738 matches (74.0% — strong). A win rate of that calibre over 738 matches is a reliable indicator of genuine quality. With 40 titles, among the most prolific champions in the Open Era: Paris NTL, Bournemouth, Roland Garros, Fort Worth NTL and 31 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Ken Rosewall has been outstanding at the Slams — 92–19 (82.9%) across 111 matches. Winning more than 7 in 10 Grand Slam matches is the benchmark of an all-time great.
69 finals reached — won 40, lost 29 (solid 58% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 110 semifinals. 141 quarterfinals.
vs. Top 10: 13–27 (32.5%, 40 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: 149–44 (77.2%); best-of-three: 388–145 (72.8%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Historic season: 1971 — 77–22 (77.8%) from 99 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.
