Overview

• Jannik Sinner stopped at 3-2 in the third set against Tallon Griekspoor after 2 hours 36 minutes, having won the first set 7-6(3) and lost the second 7-5.
• On-court treatment could not resolve severe leg cramps and he was helped off court, marking the seventh mid‑match retirement of his career.
• Under ATP rules cited in reports, cramps are not classified as an in‑play injury, limiting medical timeout options during the match.
• Tournament heat and humidity drew criticism as multiple players suffered illness or retired, with commentators calling Shanghai’s conditions brutal.
• Sinner now trails Alcaraz by 1,340 points after forfeiting 950 points and is slated to rest about a week before the Riyadh exhibition, then Vienna, Paris and the ATP Finals.
