Shao-Xuan Zeng has found hard courts difficult, recording 5–9 across 14 matches (35.7%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

vs. Top 10 on hard: 0–3 (0.0%, 3 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.

By format on hard — best-of-five: 4–3 (57.1%); best-of-three: 1–6 (14.3%). Significantly better in five-set matches — a strong physical profile on hard that tends to tell as matches and tournaments progress.

Best season: 2009 — 3–3 (50.0%) from 6 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
