Robert Lutz holds a solid hard court record of 167–100 across 267 matches (62.5%). A winning majority across 267 matches shows consistent ability to get results on hard. 7 titles on hard: Columbus, Sacramento, Boston WCT, Paris, Stowe, Cologne — a record that reflects consistent ability to close out tournaments on this surface.

At Grand Slam level (Australian Open & US Open): Robert Lutz is 6–5 (54.5%) across 11 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

11 finals reached on hard — won 7, lost 4 (solid 64% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers on hard. 22 semifinals. 37 quarterfinals.

vs. Top 10 on hard: 3–19 (13.6%, 22 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: 14–7 (66.7%); best-of-three: 146–89 (62.1%). Slightly better in five-set matches on hard — a positive sign for the Slams specifically.

Peak season: 1980 — 25–8 (75.8%) from 33 matches. That year captures the ceiling of what Robert Lutz can do on hard when performing at their best and represents the standard to aim for.
