Jorge Lozano has found hard courts difficult, recording 15–25 across 40 matches (37.5%). 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): a positive 3–2 (60.0%) across 5 matches — a player who generally rises to the occasion at the Slams on hard.

vs. Top 10 on hard: 0–6 (0.0%, 6 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: 4–6 (40.0%); best-of-three: 11–19 (36.7%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Best season: 1988 — 9–10 (47.4%) from 19 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
