At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): John Barrett has yet to record a win at Grand Slam level — 0–4 across 4 matches. Breaking through here would mark a significant step forward.
By format — best-of-five: 3–9 (25.0%); best-of-three: 14–13 (51.9%). 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 — 6–10 (37.5%) from 16 matches. The best single-season display to date — a useful reference point as the career continues to develop.
