Heading into the 2026 French Open, one question hovered over the men’s draw: Could anyone—or anything—defeat Jannik Sinner, the top-ranked Italian and overwhelming favorite?
Today, on Court Philippe-Chatrier, we got the answer. In what was less a tennis match than something resembling a UFC fight held in a sauna, Sinner fell to Juan Manuel Cerúndolo of Argentina. Sinner was also done in by a game opponent, felled by physiology that—as we know from the past—does not always accommodate brutal conditions.
