Charles Owens has a competitive clay court record of 19–21 across 40 matches (47.5%). 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): Charles Owens has yet to record a win on clay at this stage — 0–1 across 1 Grand Slam match. 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. 4 quarterfinals adds further depth to that picture.

Best season: 1976 — 4–2 (66.7%) from 6 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
