Denis Gremelmayr has a competitive clay court record of 14–16 across 30 matches (46.7%). The record shows a player capable of competing here, though there is clear room to push the win rate higher.

At Grand Slam level (Roland Garros): Denis Gremelmayr has yet to record a win on clay at this stage — 0–3 across 3 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

2 semifinals on clay without yet reaching a final — consistent deep runs that show the ability to string together wins across a full draw, with the step to the final still to come. 3 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 2–3 (40.0%, 5 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall clay court profile.

By format on clay — best-of-five: 0–3 (0.0%); best-of-three: 14–13 (51.9%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 2006 — 4–3 (57.1%) from 7 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
