Johan Kriek holds a solid hard court record of 170–103 across 273 matches (62.3%). A winning majority across 273 matches shows consistent ability to get results on hard. 5 titles on hard: Livingston, Carlsbad WCT, Johannesburg, Las Vegas — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Australian Open & US Open): a positive 31–14 (68.9%) across 45 matches — a player who generally rises to the occasion at the Slams on hard.

11 finals reached on hard — won 5, lost 6 (45% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 20 semifinals. 37 quarterfinals.

vs. Top 10 on hard: 9–24 (27.3%, 33 matches). Top 10 opponents have represented a clear ceiling on hard; addressing that deficit is the single biggest lever for improving the overall record here.

By format on hard — best-of-five: 34–18 (65.4%); best-of-three: 136–85 (61.5%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Peak season: 1979 — 16–7 (69.6%) from 23 matches. That year captures the ceiling of what Johan Kriek can do on hard when performing at their best and represents the standard to aim for.
