Torben Ulrich has found hard courts difficult, recording 22–29 across 51 matches (43.1%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

2 semifinals on hard 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.

By format on hard — best-of-five: 6–3 (66.7%); best-of-three: 16–26 (38.1%). Significantly better in five-set matches — a strong physical profile on hard that tends to tell as matches and tournaments progress.

Best season: 1968 — 13–6 (68.4%) from 19 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
