At Grand Slam level (Roland Garros): a positive 14–10 (58.3%) across 24 matches — a player who generally rises to the occasion at the Slams on clay.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Leonardo Mayer is 6–8 (42.9%) across 14 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.
