Blaz Kavcic has found clay courts difficult, recording 25–34 across 59 matches (42.4%). 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 (Roland Garros): Blaz Kavcic is 4–5 (44.4%) across 9 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 clay: 0–4 (0.0%, 4 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 9–8 (52.9%); best-of-three: 16–26 (38.1%). Significantly better in five-set matches — a strong physical profile on clay that tends to tell as matches and tournaments progress.

Best season: 2010 — 4–3 (57.1%) from 7 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
