Overview

• World No. 2 Jannik Sinner stopped at 3–2 in the deciding set against Tallon Griekspoor after roughly 2 hours 36 minutes, retiring from his third‑round match in Shanghai.
• No official medical update was issued, with reports onsite pointing to a right‑thigh cramp as the likely cause of the retirement.
• The exit prevents Sinner from defending his 2024 Shanghai title and marks his second retirement of the hard‑court swing after pulling out of the Cincinnati final.
• The tournament saw multiple retirements the same day, as Tomas Machac and David Goffin also stopped, and qualifier Valentin Vacherot advanced when Machac retired.
• With Sinner out and Alcaraz already withdrawn following his Tokyo win, the draw tilts toward Novak Djokovic—already into the last 16 and set to face Jaume Munar—and toward Alexander Zverev as leading contenders.
