Aditya Hari Sasongko has found hard courts difficult, recording 3–5 across 8 matches (37.5%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar.

By format on hard — best-of-five: 0–4 (0.0%); best-of-three: 3–1 (75.0%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on hard.
