Jose-Luis Clerc has an impressive career record of 381–152 across 533 matches (71.5% — strong). A win rate of that calibre over 533 matches is a reliable indicator of genuine quality. With 25 titles, among the most prolific champions in the Open Era: Florence, Buenos Aires, Santiago, Johannesburg-1 and 15 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): a positive 33–23 (58.9%) across 56 matches — a player who generally rises to the occasion at the Slams.
36 finals reached — won 25, lost 11 (solid 69% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 61 semifinals. 80 quarterfinals.
vs. Top 10: 24–46 (34.3%, 70 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: 56–40 (58.3%); best-of-three: 325–112 (74.4%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Historic season: 1980 — 73–23 (76.0%) from 96 matches. A campaign of 73 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.
Jose-Luis Clerc assembled a remarkable 28-match winning streak — a run of that length goes far beyond form and into a different level of dominance.
