Andy Roddick has been dominant on hard, posting 426–138 across 564 matches (75.5% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career on hard. With 21 titles, among the most prolific hard court champions in the Open Era: Washington, Memphis, Indianapolis, Canada Masters and 8 more.

At Grand Slam level (Australian Open & US Open): Andy Roddick has been outstanding — 81–23 (77.9%) across 104 matches. Winning more than 7 in 10 Grand Slam matches on hard is the benchmark of an all-time great on this surface.

ATP Masters 1000 on hard (Indian Wells, Miami, Canada, Cincinnati, Shanghai, Paris): Andy Roddick is elite here — 128–50 (71.9%) across 178 matches. Sustaining that win rate in the Tour's deepest regular-week draws is a defining quality of the very best on this surface.

36 finals reached on hard — won 21, lost 15 (solid 58% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on hard. 64 semifinals. 93 quarterfinals.

vs. Top 10 on hard: 35–50 (41.2%, 85 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: 97–26 (78.9%); best-of-three: 329–112 (74.6%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Dominant season: 2004 — 57–11 (83.8%) from 68 matches. A campaign of 57 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.

Andy Roddick assembled a remarkable 20-match winning streak on hard — a run of that length goes far beyond form and into a different level of dominance on this surface.
