Overview

• World No. 2 Jannik Sinner beat Daniel Altmaier 6-3, 6-3 in 1 hour 38 minutes to reach the third round and will face Tallon Griekspoor, whom he leads 6-0 head-to-head.
• Coming off the China Open title, Sinner said he had little time to adjust to Shanghai but added that he adapts to whatever conditions he finds.
• Alexander Zverev advanced 6-4, 6-4 over Valentin Royer and took a medical timeout for a toe issue late in the match.
• Zverev accused tournament directors of slowing courts to benefit Sinner and Alcaraz; multiple reports cited Shanghai’s Court Pace Index dropping from roughly 40–42 in prior years to about 32.8–32.9 in 2025.
• Asked about the claims, Sinner said players do not decide court speeds and that he focuses on adapting, while other results included wins for Alex de Minaur and Daniil Medvedev and an upset of Andrey Rublev by Yoshihito Nishioka.
