Vitas Gerulaitis has an impressive career record of 535–232 across 767 matches (69.8% — strong). A win rate of that calibre over 767 matches is a reliable indicator of genuine quality. With 26 titles, among the most prolific champions in the Open Era: Vienna, New York, St. Louis WCT, Ocean City and 20 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 86–37 (69.9%) across 123 matches — a player who generally rises to the occasion at the Slams.
56 finals reached — won 26, lost 30 (46% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 95 semifinals. 124 quarterfinals.
vs. Top 10: 48–75 (39.0%, 123 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: 109–55 (66.5%); best-of-three: 426–176 (70.8%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Historic season: 1979 — 76–23 (76.8%) from 99 matches. A campaign of 76 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.
