Yen-Hsun Lu has found grass courts difficult, recording 28–37 across 65 matches (43.1%). 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 (Wimbledon): Yen-Hsun Lu is 11–15 (42.3%) across 26 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

vs. Top 10 on grass: 3–6 (33.3%, 9 matches). Top 10 opponents have represented a clear ceiling on grass; addressing that deficit is the single biggest lever for improving the overall record here.

By format on grass — best-of-five: 12–16 (42.9%); best-of-three: 16–21 (43.2%). Consistent regardless of format on grass — a sign of a well-rounded game that holds up as matches develop.

Best season: 2010 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
