Ivan Lendl has had a dominant career, posting 1068–242 across 1310 matches (81.5% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career. With 92 titles, among the most prolific champions in the Open Era: Masters, Houston WCT, Toronto, Barcelona and 55 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Ivan Lendl has been outstanding at the Slams — 222–49 (81.9%) across 271 matches. Winning more than 7 in 10 Grand Slam matches is the benchmark of an all-time great.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): a positive 25–20 (55.6%) across 45 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
145 finals reached — won 92, lost 53 (solid 63% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 190 semifinals. 214 quarterfinals.
vs. Top 10: 164–93 (63.8%, 257 matches). Winning above .500 against the world's best is a benchmark of genuine elite quality on Tour.
By format — best-of-five: 307–78 (79.7%); best-of-three: 761–164 (82.3%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Historic season: 1980 — 110–28 (79.7%) from 138 matches. A campaign of 110 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.
Ivan Lendl assembled a historic 44-match winning streak — one of the longest in the Open Era. Sustaining that level across so many matches demands physical and mental consistency that very few players have matched.
