Ryan Harrison has found clay courts difficult, recording 14–27 across 41 matches (34.1%). 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): Ryan Harrison has struggled at Grand Slam level on clay: 1–5 (16.7%) in 6 matches. The best-of-five format and elite fields make this the toughest benchmark on this surface.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Ryan Harrison is 5–6 (45.5%) across 11 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.

vs. Top 10 on clay: 0–7 (0.0%, 7 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 1–6 (14.3%); best-of-three: 13–21 (38.2%). 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: 2012 — 5–7 (41.7%) from 12 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
