Overview

• Arthur Rinderknech collapsed under 32°C conditions during his match with Félix Auger-Aliassime and retired at 7-6(4), 4-2, sending Auger-Aliassime into the round of 16.
• Tournament organisers implemented the ATP’s formal heat rule on Monday to allow extra cooling breaks but have faced criticism from former coaches for inadequate player protections.
• Competitors resorted to improvised cooling methods—including ice towels, portable fans and even placing a head inside a court-side refrigerator—to combat oppressive late-summer temperatures.
• Heavy rain on Tuesday forced multiple match suspensions at the Linder Family Tennis Center and further disrupted the tournament schedule.
• Broadcasts and social media clips of on-court medical interventions have intensified calls for the ATP to review late-season scheduling to safeguard player welfare before the US Open.
