Jason Jung has found the Tour difficult, recording 11–26 across 37 matches (29.7%). 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): Jason Jung has yet to record a win at Grand Slam level — 0–3 across 3 matches. Breaking through here would mark a significant step forward.
By format — best-of-five: 0–6 (0.0%); best-of-three: 11–20 (35.5%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Best season: 2019 — 3–6 (33.3%) from 9 matches. The best single-season display to date — a useful reference point as the career continues to develop.
