Sinner Resting After Shanghai Heat Scare as Pressure Mounts on ATP to Add Heat Rule

The WTA’s heat protocol, used to halt a Wuhan match, underscores the ATP’s lack of objective thresholds for suspending play in extreme conditions.

Overview

  • Jannik Sinner withdrew in the Shanghai third round with severe cramping and has returned to Monte Carlo, where federation outlet Supertennis says he needs only a few days of rest.
  • Shanghai’s tournament saw peaks near 33°C with humidity above 85%, with perceived temperatures close to 40°C and at least seven retirements before the end of the third round.
  • Novak Djokovic vomited on court during his match, Terence Atmane collapsed, and other players including Taylor Fritz and Alexander Zverev reported heat-related difficulties.
  • The WTA applied its WBGT-based Heat Rule to suspend a Wuhan match, highlighting a clear contrast with the ATP, which has not implemented an equivalent policy.
  • Players and commentators are urging the ATP to adopt WBGT thresholds and standardized safeguards, as debate intensifies over scheduling, recovery time, and the limits of relying on stadium roofs.
