Joao Fonseca’s Miami Open campaign came to an end in the second round after losing the highly anticipated matchup with Carlos Alcaraz.
In their maiden career clash, Alcaraz defeated Fonseca in straight sets, winning 6-4, 6-4 to advance to round three, where he will face Sebastian Korda.
The Brazilian has now faced the Spaniard and Jannik Sinner for the first time in the past two tournaments, having fallen to the Italian at the Indian Wells Open.

Or do you think both Sabalenka and Sinner will win the Miami Open?
Fonseca was competitive against both of the ‘new two’ but failed to get a set off either of them.
After his loss to Alcaraz, the 19-year-old took to social media to send a message to his conqueror.

“These matches motivate me to keep working. Thank you all for the constant support.”

Joao Fonseca’s ranking after bowing out of the Miami Open
Though it was only his second-ever appearance at the Miami Open, Fonseca’s finish at the 2026 edition of the tournament was worse than in his first in 2025.
Fonseca reached the third round of the Miami Open last year, beating Learner Tien and Ugo Humbert before losing to Alex de Minaur.
With his second-round exit this time around, Fonseca will lose 20 ranking points following the conclusion of the Miami Open.
The decrease is not enough to see a shift in his live ranking at the moment, which is currently number 39 in the world.
Fonseca will need to be within the top 32 to be seeded for Roland Garros, set to get underway in May.
