Danilo Marcelino has found hard courts difficult, recording 22–38 across 60 matches (36.7%). 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 (Australian Open & US Open): 1–2 across just 3 matches — still very early days at this level on hard.

2 semifinals on hard 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.

By format on hard — best-of-five: 1–3 (25.0%); best-of-three: 21–35 (37.5%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.

Best season: 1988 — 6–4 (60.0%) from 10 matches. The best single-season display to date — a useful reference point as the hard record continues to develop.
