At Grand Slam level (Wimbledon): Pierre Barthes is 15–12 (55.6%) across 27 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

3 finals reached on grass — none converted into a title yet. Reaching 3 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 3 semifinals. 5 quarterfinals.

By format on grass — best-of-five: 16–14 (53.3%); best-of-three: 25–18 (58.1%). Slightly stronger in three-set contests on grass, though the five-set record is still respectable.
