Unseeded Argentinian Juan Manuel Cerundolo notched the biggest win of his career in the second round of Thursday’s French Open, stunning World No. 1 Jannik Sinner in five sets, 3-6, 2-6, 7-5, 6-1, 6-1.Cerundolo won 15 consecutive points in the third set to force a fourth, leading to Sinner struggling with his fitness in the final two sets. At one point in the third set, Sinner led 5-1 before asking to speak with the umpire for a dehydration-related timeout. The umpire allowed a medical timeout and granted Sinner to briefly leave the court. During the TNT broadcast, commentator Jim Courier scorched the umpire for allowing Sinner’s timeout. Players are usually not allowed to take a medical timeout due to cramping, which is what Sinner asked for after noticeably moving slower in the third set.
“That’s not fair. That’s not right,” Courier mentioned. “We love the top players, they drive the sport, but you’ve gotta apply the rules fairly. The rules are being bent for the top players.”Earlier this year against Daniil Medvedev at the 2026 Italian Open, Sinner began struggling with cramping before he asked for a timeout. Medvedev slammed the move after the loss and mentioned the tour is giving preferential treatment to its top players.It was Sinner’s first loss on tour since February, snapping a 30-match winning streak. He was looking to complete the career Grand Slam and entered the tournament as a near -300 favorite to do so, thanks in part to his rival, Carlos Alcaraz, missing the event with injury.
