Gastao Elias has found clay courts difficult, recording 23–29 across 52 matches (44.2%). 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): Gastao Elias 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. 6 quarterfinals adds further depth to that picture.

By format on clay — best-of-five: 3–3 (50.0%); best-of-three: 20–26 (43.5%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 2013 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
