John Brown has a competitive career record of 19–22 across 41 matches (46.3%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): John Brown is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
By format — best-of-five: 6–10 (37.5%); best-of-three: 13–12 (52.0%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Best season: 1968 — 12–12 (50.0%) from 24 matches. The best single-season display to date — a useful reference point as the career continues to develop.
