Bruce Manson has found clay courts difficult, recording 35–48 across 83 matches (42.2%). 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): Bruce Manson is 6–9 (40.0%) across 15 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on clay: 1–9 (10.0%, 10 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: 5–6 (45.5%); best-of-three: 30–42 (41.7%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1980 — 8–6 (57.1%) from 14 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
