Frew McMillan has found clay courts difficult, recording 47–66 across 113 matches (41.6%). 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): Frew McMillan is 8–8 (50.0%) across 16 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 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. 4 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 0–4 (0.0%, 4 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: 12–17 (41.4%); best-of-three: 35–49 (41.7%). Consistent regardless of format on clay — a sign of a well-rounded game that holds up as matches develop.

Best season: 1977 — 5–4 (55.6%) from 9 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
