Brazilian wonderkid João Fonseca (99 ATP singles ranked) made history on Sunday when he beat Argentina’s Francisco Cerúndolo (28) 6-4, 7-6 (1) to become the 2025 Argentina Open champion. At 18 years and 5 months old, the Brazilian became the youngest player to win the tournament, beating current world number three Carlos Alcaraz’s record by a year and four months.

“This tournament was a big step for me,” said Fonseca after the match. “When you get here, you take a look at the draw and think ‘It’s impossible to win this,’ and here we are. It’s a very important title for me, the first one, and it’ll be forever in my heart.”

It was a tense match from the get-go. With tickets sold out (5,746 fans in attendance), the big contingent of Brazilian fans in the stands kept the Argentine crowd in check.

Cerúndolo started off very erratic, with a series of unforced errors costing him his serve in the first game.........
