The 19-year-old Brazilian Fonseca, surging on debut with straight-set wins over Gabriel Diallo and Arthur Rinderknech in the prior 48 hours, showcased aggressive baseline play and momentum toward his first Masters 1000 quarterfinal. Berrettini's recent Indian Wells cramping raised fitness questions, while steady Monte Carlo conditions favored endurance over power, shaping a competitive trader consensus on the Italian's experience versus the teenager's upset potential.
