Tony Mmoh has found hard courts difficult, recording 10–17 across 27 matches (37.0%). 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 (Australian Open & US Open): Tony Mmoh is 2–2 (50.0%) across 4 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on hard — best-of-five: 4–4 (50.0%); best-of-three: 6–13 (31.6%). Significantly better in five-set matches — a strong physical profile on hard that tends to tell as matches and tournaments progress.

Best season: 1988 — 4–3 (57.1%) from 7 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
