Pete Sampras has been dominant on hard, posting 429–103 across 532 matches (80.6% — exceptional). Few players in the Open Era have sustained that level of dominance across a full career on hard. With 36 titles, among the most prolific hard court champions in the Open Era: ATP Tour World Championships, ATP Tour World Championship, Sydney Outdoor, Australian Open and 14 more.

At Grand Slam level (Australian Open & US Open): Pete Sampras has been outstanding — 116–18 (86.6%) across 134 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): Pete Sampras is elite here — 125–37 (77.2%) across 162 matches. Sustaining that win rate in the Tour's deepest regular-week draws is a defining quality of the very best on this surface.

48 finals reached on hard — converted 36 into titles (outstanding 75% conversion rate). Converting finals at that rate separates champions from contenders. 67 semifinals. 82 quarterfinals.

vs. Top 10 on hard: 62–36 (63.3%, 98 matches). Winning above .500 against the world's best on hard is a benchmark of genuine elite quality on this surface.

By format on hard — best-of-five: 129–22 (85.4%); best-of-three: 300–81 (78.7%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Dominant season: 1994 — 37–3 (92.5%) from 40 matches. A campaign of 37 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.

Historic: 34 consecutive wins on hard — one of the longest winning streaks on this surface in the Open Era. To sustain that level across so many matches demands physical and mental consistency that very few players in history have matched.
