Jim Gurfein has found clay courts difficult, recording 21–26 across 47 matches (44.7%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Roland Garros): 1–1 across just 2 matches — still very early days at this level on clay.

5 quarterfinals on clay, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.

vs. Top 10 on clay: 0–3 (0.0%, 3 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.

Best season: 1983 — 9–7 (56.3%) from 16 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
