Daniel Brands has found clay courts difficult, recording 21–34 across 55 matches (38.2%). 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): Daniel Brands has yet to record a win on clay at this stage — 0–6 across 6 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. 5 quarterfinals adds further depth to that picture.

vs. Top 10 on clay: 3–3 (50.0%, 6 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: 0–6 (0.0%); best-of-three: 21–28 (42.9%). 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: 2009 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
