Pieter Aldrich has found hard courts difficult, recording 21–26 across 47 matches (44.7%). 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): Pieter Aldrich is 4–4 (50.0%) across 8 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 hard: 0–5 (0.0%, 5 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: 6–6 (50.0%); best-of-three: 15–20 (42.9%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Best season: 1988 — 11–10 (52.4%) from 21 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
