Jannik Sinner, the world number one and French Open title favourite, is eliminated in the second round after a five-set defeat by Argentina’s Juan Manuel Cerúndolo. Multiple outlets report that Sinner led in the match, including a 5-1 advantage in the third set, but he eventually lost 3-6, 2-6, 7-5, 6-1, 6-1. The defeat ends Sinner’s bid to win his first French Open title and complete a career Grand Slam. Several reports attribute the collapse to physical problems during the match, citing cramping when serving for the match, illness, dizziness, and difficulty coping with heat conditions at Roland Garros. One outlet explicitly says Sinner denies heat was the cause of the shock exit, but other sources continue to reference the impact of heat and associated symptoms. The loss also follows mention that the tournament’s main draw landscape had changed, with Carlos Alcaraz absent due to injury, increasing expectations around Sinner’s chances. Overall, sources agree on the result, the five-set nature of the match, and Sinner’s second-round exit as the major upset.
