At Grand Slam level (Roland Garros): Philipp Kohlschreiber is 16–17 (48.5%) across 33 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): a positive 39–34 (53.4%) across 73 matches — winning above .500 at this level, week in week out, is a genuine sign of quality on clay.

14 finals reached on clay — won 6, lost 8 (43% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 17 semifinals. 29 quarterfinals.

vs. Top 10 on clay: 6–33 (15.4%, 39 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: 23–22 (51.1%); best-of-three: 155–117 (57.0%). Slightly stronger in three-set contests on clay, though the five-set record is still respectable.
