Schalk Van Der Merwe has found the Tour difficult, recording 10–20 across 30 matches (33.3%). 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): a positive 3–2 (60.0%) across 5 matches — a player who generally rises to the occasion at the Slams.
By format — best-of-five: 3–2 (60.0%); best-of-three: 7–18 (28.0%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1982 — 6–11 (35.3%) from 17 matches. The best single-season display to date — a useful reference point as the career continues to develop.
