Brazilian teenager Joao Fonseca defeated 39-year-old Novak Djokovic in the third round of the 2026 French Open in Paris on May 29 after nearly five hours of play. Fonseca won 4-6, 4-6, 6-3, 7-5, 7-5, marking the first time a teenager has beaten Djokovic in a Grand Slam match [1, 2, 3, 4]. The match lasted 4 hours and 53 minutes, showcasing a remarkable comeback by the 19-year-old [1, 4, 5]. Djokovic was attempting to claim a record 25th Grand Slam singles title but exited the tournament with 24 titles to his name [1, 2, 3, 4]. After the loss, Djokovic expressed uncertainty about his future participation at Roland Garros, saying simply, "I don’t know" and congratulated Fonseca, calling his performance "unbelievable" [3].
Fonseca carried his momentum into the fourth round on May 31, defeating two-time French Open finalist Casper Ruud, the 15th seed, to reach his first Grand Slam quarter-final [6, 7]. The young Brazilian said, "I actually didn't believe I could win the match. I just played and enjoyed being in the court," reflecting the unexpected nature of his breakthrough [5].
In the quarter-finals on June 2, Fonseca faced Czech Jakub Mensik, who became the youngest Czech man to reach a Grand Slam semi-final by defeating Fonseca in straight sets, 6-4, 6-3, 7-6(3) [8, 9, 10]. Fonseca acknowledged the lessons learned from the event: "This tournament gives me more conviction and more confidence to keep going and for sure understanding a little bit more body and my limits" [9].
Alexander Zverev, 29, defeated Mensik on June 7 with a 7-5, 6-2, 3-6, 6-3 victory to secure a place in the French Open final [10, 11]. Zverev said he remains focused, stating, "I focus on next match, and I focus on the opponent as they cross the net, and that's the only thing that I can control" [10]. He will face either Flavio Cobolli or Matteo Arnaldi for the title [11].
World number one Jannik Sinner was eliminated earlier in the tournament, and defending champion Carlos Alcaraz withdrew due to injury [1, 2, 12, 10].
