ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Andreas Haider-Maurer is elite here — 2–1 (66.7%) across 3 matches. Sustaining that win rate in the Tour's deepest regular-week draws is a defining quality of the very best on this surface.

5 quarterfinals on clay, including one run to the semifinal — regularly reaching that stage is a solid baseline, with the next step being to break through to the final rounds more often.
