Overview

• Novak Djokovic defeated Jaume Munar 6-3, 5-7, 6-2, taking multiple medical timeouts for a left-leg/ankle issue and having his vitals checked in sweltering humidity.
• Djokovic had vomited during his previous match against Yannick Hanfmann, and he briefly collapsed after the second set against Munar before rallying in the decider.
• The 38-year-old became the oldest player to reach an ATP Masters 1000 quarter-final and remains on course for a record-extending fifth Shanghai title.
• Extreme heat and humidity have driven injuries and retirements, including defending champion Jannik Sinner’s cramp-induced withdrawal, with Holger Rune urging a formal heat policy.
• The ATP said it would consider introducing a heat rule; Djokovic next plays Zizou Bergs after the Belgian edged Gabriel Diallo in a final-set tiebreak, with Carlos Alcaraz absent from the event.
