Peter Gojowczyk has reached 1 final without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Peter Gojowczyk has yet to record a win on clay at this stage — 0–4 across 4 Grand Slam matches. Breaking through here would mark a significant step forward on this surface.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Peter Gojowczyk is 2–3 (40.0%) across 5 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.

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. 1 semifinal. 1 quarterfinal.

By format on clay — best-of-five: 0–4 (0.0%); best-of-three: 7–13 (35.0%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance on clay.

Best season: 2018 — 6–7 (46.2%) from 13 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
