Tian C. Viljoen
Tian C. Viljoen has found the Tour difficult, recording 5–7 across 12 matches (41.7%). 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): 1–1 across just 2 matches — still very early days at this level.
Best season: 1981 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the career continues to develop.
