By format on clay — best-of-five: 0–3 (0.0%); best-of-three: 6–20 (23.1%). 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: 1983 — 3–6 (33.3%) from 9 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
