Joao Fonseca matches 21-year Nadal record at Monte Carlo Masters

Joao Fonseca has pulled off something we haven’t seen since Rafael Nadal at the Monte Carlo Masters.

The Brazilian teenager hasn’t had the smoothest start to 2026, but there were signs of progress during the Sunshine Double, where only Jannik Sinner and Carlos Alcaraz managed to stop him.

There’s already a lot of hype around Fonseca, with many expecting him to go far in the sport.

Despite the attention, he seems comfortable with it all. His recent win over Arthur Rinderknech at Monte Carlo was another step forward.

Joao Fonseca matches Rafael Nadal’s feat in Monte Carlo with impressive run

Fonseca secured a 7-5, 4-6, 6-3 win over Rinderknech to follow up his opening-round victory against Gabriel Diallo.

It’s only the second time in his career that Fonseca has reached the last 16 of an ATP 1000 event, and he’s done it on his first appearance at the Monte Carlo Masters.

At just 19 years old, Fonseca is now the youngest player to reach this stage of the tournament since 2005.

Nadal had actually already hit this milestone two years earlier when he was just 16.

Carlos Alcaraz didn’t make it this far in Monte Carlo until he won the title at age 21.

How Rafael Nadal and Richard Gasquet performed at the 2005 Monte Carlo Masters

Fonseca will be hoping to follow in the footsteps of both Nadal and Gasquet, who did not stop at just the last-16 stage of the 2005 Monte Carlo Masters.

Gasquet had come through qualifying that year, before beating top seed Roger Federer and 10th seed Nikolay Davydenko to reach the semifinals.

This is where the Frenchman would lose to 11th seed and fellow 18-year-old Nadal, who would subsequently reach his first final at the Monte Carlo Masters that year.

Nadal beat Guillermo Coria 6-3, 6-1, 0-6, 7-5 in the final as he claimed his maiden ATP 1000 title and first of a record 11 titles at Monte Carlo Masters.

The Spaniard would go on to win his first Roland Garros title later that year.

While Fonseca may not be able to replicate what Nadal did in his career, he does now have an opportunity in Monte Carlo this week. Fonseca will play Matteo Berrettini for a place in his first quarter-final appearance at a Masters event after he was drawn against former Wimbledon finalist Matteo Berrettini following Daniil Medvedev’s shock defeat.
