Ernests Gulbis has found grass courts difficult, recording 15–24 across 39 matches (38.5%). 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): Ernests Gulbis is 11–12 (47.8%) across 23 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: 3–4 (42.9%, 7 matches). Competitive against the elite, but still narrowly below .500 — closing that gap would directly elevate the overall grass court profile.

By format on grass — best-of-five: 11–12 (47.8%); best-of-three: 4–12 (25.0%). Significantly better in five-set matches — a strong physical profile on grass that tends to tell as matches and tournaments progress.

Best season: 2008 — 3–2 (60.0%) from 5 matches. The best single-season display to date — a useful reference point as the grass record continues to develop.
