Sinner Retires, Ends Shanghai Title Defense

Defending Shanghai champion Jannik Sinner retired during his third-round match against Tallon Griekspoor at the Shanghai Masters due to severe cramping in his right leg, ending his bid to defend the title. He stopped the match at 6-7(3), 7-5, 3-2 after trying to play through the problem and receiving on-court treatment, and required assistance to leave the court. Tallon Griekspoor advanced to the fourth round and will face qualifier Valentin Vacherot. Sinner had arrived in Shanghai fresh off a China Open title and was aiming to close the gap on world No. 1 Carlos Alcaraz, who did not play Shanghai, so the withdrawal is a significant blow to his autumn schedule. It is unclear whether Sinner will compete in the upcoming Six Kings Slam exhibition in Saudi Arabia or fulfil immediate media duties as he recovers; further updates are awaited.
