Johan Kriek has a competitive clay court record of 24–26 across 50 matches (48.0%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Roland Garros): Johan Kriek is 4–3 (57.1%) across 7 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 semifinals on clay without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 6 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 0–4 (0.0%, 4 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 4–3 (57.1%); best-of-three: 20–23 (46.5%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 1986 — 4–1 (80.0%) from 5 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
