Jay Royappa has found grass courts difficult, recording 1–5 across 6 matches (16.7%). 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 (Wimbledon): 1–2 across just 3 matches — still very early days at this level on grass.

By format on grass — best-of-five: 1–2 (33.3%); best-of-three: 0–3 (0.0%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.
