Dick R. Bohrnstedt has found hard courts difficult, recording 18–23 across 41 matches (43.9%). 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. 5 quarterfinals adds further depth to that picture.

vs. Top 10 on hard: 0–5 (0.0%, 5 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.

Best season: 1973 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
