Martin Strelba has found clay courts difficult, recording 38–47 across 85 matches (44.7%). The numbers point to a surface that has not consistently suited the game — a key area of opportunity on the calendar. Martin Strelba has reached 1 final without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): 1–2 across just 3 matches — still very early days at this level on clay.

One final reached on clay, without converting it into a title. That final-round experience is valuable groundwork for going one step further next time. 2 semifinals. 9 quarterfinals.

By format on clay — best-of-five: 1–2 (33.3%); best-of-three: 37–45 (45.1%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Peak season: 1989 — 16–14 (53.3%) from 30 matches. That year captures the ceiling of what Martin Strelba can do on clay when performing at their best and represents the standard to aim for.
