Boris Becker has had a dominant career, posting 713–214 across 927 matches (76.9% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career. With 49 titles, among the most prolific champions in the Open Era: Masters, ATP Tour World Championships, ATP World Tour Championships, Milan and 29 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Boris Becker has been outstanding at the Slams — 163–40 (80.3%) across 203 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): Boris Becker is elite here — 97–43 (69.3%) across 140 matches. Sustaining that win rate in the Tour's deepest regular-week draws is a defining quality of the very best.
78 finals reached — won 49, lost 29 (solid 63% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 112 semifinals. 130 quarterfinals.
vs. Top 10: 121–65 (65.1%, 186 matches). Winning above .500 against the world's best is a benchmark of genuine elite quality on Tour.
By format — best-of-five: 223–60 (78.8%); best-of-three: 490–154 (76.1%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Historic season: 1990 — 71–15 (82.6%) from 86 matches. A campaign of 71 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.
Boris Becker assembled a remarkable 21-match winning streak — a run of that length goes far beyond form and into a different level of dominance.
