Johan Van Herck has a competitive clay court record of 26–29 across 55 matches (47.3%). 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 Van Herck is 3–4 (42.9%) across 7 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

3 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. 5 quarterfinals adds further depth to that picture.

By format on clay — best-of-five: 6–7 (46.2%); best-of-three: 20–22 (47.6%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Best season: 1996 — 9–9 (50.0%) from 18 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
