Sinner was leading 6-3, 6-2, 5-1 and appeared on the verge of victory before suddenly wilting in temperatures exceeding 30 degrees Celsius. He took a medical timeout, reporting feelings of sickness and dizziness, and upon returning, his movement, timing, and power were significantly impaired. Cerundolo capitalised on Sinner's collapse, completing an astonishing comeback with a final score of 3-6, 2-6, 7-5, 6-1, 6-1. This defeat ends Sinner's impressive 30-match winning streak and leaves the French Open wide open, especially with Carlos Alcaraz absent due to injury.
