Robert Rheinberger has found the Tour difficult, recording 4–31 across 35 matches (11.4%). 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): Robert Rheinberger 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: 0–5 (0.0%); best-of-three: 4–26 (13.3%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Best season: 1974 — 2–6 (25.0%) from 8 matches. The best single-season display to date — a useful reference point as the career continues to develop.
