Bill Scanlon has found clay courts difficult, recording 33–47 across 80 matches (41.3%). 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): Bill Scanlon is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

4 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: 1–7 (12.5%, 8 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: 2–5 (28.6%); best-of-three: 31–42 (42.5%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 1983 — 6–5 (54.5%) from 11 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
