Brazilian teenager Joao Fonseca reached his first Grand Slam quarterfinal on Sunday, beating two-time French Open finalist Casper Ruud 7-5, 7-6(8), 5-7, 6-2 in a nearly four-hour battle on Court Philippe-Chatrier at Roland Garros.
The win made the 19-year-old the first Brazilian man to reach the quarterfinals in Paris since Gustavo Kuerten in 2004. Kuerten, a three-time Roland Garros champion and former world No. 1, watched from the stands as his young countryman closed out the biggest clay-court result of his career.
The victory came just two days after Fonseca rallied from two sets down to stun 24-time major champion Novak Djokovic, one of the signature upsets of the tournament. Against Ruud, the 28th seed again paired a ferocious forehand with sharp defense to grind down a more experienced opponent who had reached the Roland Garros final in both 2022 and 2023.
The match was as close as the scoreline was not. Both men struck 51 winners and committed 52 unforced errors, according to Infosys Stats, leaving the result to be decided in the biggest moments — where the younger player held firm. Fonseca did not hit a single double fault across the four sets, converted four of his 13 break points, and won 156 total points to Ruud’s 144.
The turning point came in a tense second-set tiebreak. With Ruud holding set points, Fonseca rushed the net behind his serve and put away a drop volley, then sealed the breaker 10-8. He followed the same aggressive blueprint on match point, charging forward for a volley winner.
“I played really good in the important moments,” Fonseca said after the win, adding that he tried to bring energy and entertainment to the court. Throughout the night, fans in the neon yellow of Brazil’s national soccer team chanted his name after every big point. Fonseca said it meant even more to win with Kuerten courtside, calling the former champion “an idol for our sport and for our country.”
Fonseca now advances to face 20-year-old Jakub Mensik of the Czech Republic, who reached his own maiden Grand Slam quarterfinal by holding off Andrey Rublev 6-3, 7-6(6), 4-6, 2-6, 6-3. Mensik became the youngest Czech man to reach a major quarterfinal since Ivan Lendl in 1980.
The pairing underlines a striking youth surge in the bottom half of the men’s draw. Nineteen-year-old Spaniard Rafael Jodar also reached the last 16 with a comeback from two sets down and will meet second seed Alexander Zverev, the only established contender still standing in that section after the early exits of several top names.
