The 2025 French Open delivered one of the most stunning upsets in modern Grand Slam tennis on Thursday, when men’s top seed Jannik Sinner saw his 30-match winning streak and title hopes collapse amid a sudden heat-related health crisis and a dramatic comeback from unseeded Argentinian Juan Manuel Cerundolo. The shocking exit has blown the men’s draw wide open, as the tour’s top competitor exited the tournament earlier than any other major since last year’s Roland Garros.
