At Grand Slam level (Roland Garros): Robert Lutz is 7–7 (50.0%) across 14 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

2 finals reached on clay — none converted into a title yet. Reaching 2 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 2 semifinals. 8 quarterfinals.

vs. Top 10 on clay: 1–6 (14.3%, 7 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 6–6 (50.0%); best-of-three: 53–46 (53.5%). Slightly stronger in three-set contests on clay, though the five-set record is still respectable.
