Francisco Cerúndolo advances to the quarterfinals of the ATP 500 in Rio de Janeiro. Argentina's number 1 tennis player is slowly rediscovering his game after a difficult start to 2024.

The bad news of the day was the early elimination of Horacio Zeballos in the doubles draw. At the bottom of the table, the 17-year-old Brazilian Joao Fonseca got the first ATP victory of his career and became the first player born in 2006 to win on the big tennis circuit.
