David Nalbandian has an impressive hard court record of 187–98 across 285 matches (65.6% — strong). A win rate of that calibre over 285 matches is a reliable indicator of genuine quality on this surface. 5 titles on hard: Madrid Masters, Paris Masters, Stockholm, Sydney, Washington — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Australian Open & US Open): a positive 47–20 (70.1%) across 67 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 81–47 (63.3%) across 128 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on hard.

10 finals reached on hard — won 5, lost 5 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on hard. 16 semifinals. 33 quarterfinals.

vs. Top 10 on hard: 22–32 (40.7%, 54 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall hard court profile.

By format on hard — best-of-five: 54–22 (71.1%); best-of-three: 133–76 (63.6%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Peak season: 2008 — 24–8 (75.0%) from 32 matches. That year captures the ceiling of what David Nalbandian can do on hard when performing at their best and represents the standard to aim for.
