Flavio Cobolli, the 10th seed, defeated fourth-seeded Felix Auger-Aliassime 4-6, 6-4, 6-4, 6-4 in the French Open quarter-finals on June 3, 2026, securing his first Grand Slam semi-final appearance [1, 2, 3, 4]. The 24-year-old Italian came back from a set and a break down in a match lasting around three hours and 24 minutes [2, 4].
The match started outdoors amid windy conditions on Court Philippe Chatrier. After the first set, the roof was closed due to the weather, changing the playing environment [1, 2, 3, 4]. Cobolli described the first set as "incredibly windy" and "really tough to play," saying, "I think we played two different matches today" [2].
Auger-Aliassime served well early and was seen as a favorite following the early exit of fellow top Italian Jannik Sinner in the second round [1, 2, 4]. However, Cobolli adjusted his game, later saying he "went to the toilet to think a bit" and reminded himself, "this is the best court I've played on in my life, because I can show my best tennis" [2]. He added, "I must give everything in all my matches. So today I'm really happy" [2].
Cobolli's victory guarantees an all-Italian men’s semi-final at Roland Garros. He will face the winner of the quarter-final between Matteo Berrettini and Matteo Arnaldi, scheduled next in the draw [1, 2, 3, 4]. Cobolli said regarding his next opponent, "I don't care which Matteo is in the semi-finals. It's been the best week of my life but I'm still missing something, so I have to fight again" [2].
After this result, Cobolli will enter the top 10 of the world rankings unless Jakub Mensik wins the tournament [2, 4]. The tournament progresses with the Berrettini-Arnaldi quarter-final determining Cobolli's semi-final opponent.
