At Grand Slam level (Australian Open & US Open): a positive 45–29 (60.8%) across 74 matches — a player who generally rises to the occasion at the Slams on hard.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): a positive 84–75 (52.8%) across 159 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on hard.

vs. Top 10 on hard: 24–60 (28.6%, 84 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: 47–30 (61.0%); best-of-three: 254–195 (56.6%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Dominant season: 2009 — 34–15 (69.4%) from 49 matches. A campaign of 34 wins on hard in a single season is among the best single-season records the surface has seen — the clearest benchmark of what is achievable at peak level.
