Ken Flach has found the Tour difficult, recording 52–80 across 132 matches (39.4%). The numbers point to a player still building their Tour presence — a key area of opportunity going forward.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Ken Flach is 21–19 (52.5%) across 40 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): a positive 2–2 (50.0%) across 4 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
vs. Top 10: 0–9 (0.0%, 9 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: 23–21 (52.3%); best-of-three: 29–59 (33.0%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1985 — 12–12 (50.0%) from 24 matches. The best single-season display to date — a useful reference point as the career continues to develop.
