Overview

• Trailing 6-7 (3), 7-5, 3-2, Jannik Sinner stopped with severe thigh cramping against Tallon Griekspoor, who advanced to the fourth round.
• Novak Djokovic battled past qualifier Yannick Hanfmann 4-6, 7-5, 6-3 to reach the last 16 and called the heat and humidity "brutal."
• Players and organizers contended with punishing conditions that contributed to retirements and on-court medical episodes across the day.
• Sinner’s exit means he retains only 50 points from Shanghai, a roughly 950-point drop that weakens his chase of Carlos Alcaraz, who withdrew before the event.
• The field opened further as Giovanni Mpetshi Perricard upset No. 4 Taylor Fritz, with other seeds tested in the steamy conditions.
