Tobias Kamke has found clay courts difficult, recording 16–28 across 44 matches (36.4%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

At Grand Slam level (Roland Garros): Tobias Kamke is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

By format on clay — best-of-five: 4–6 (40.0%); best-of-three: 12–22 (35.3%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 2014 — 4–4 (50.0%) from 8 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
