Wimbledon Qualifying Suspended After Electronic Line-Calling Fails in Heat

Organisers' reliance on automated line calling under a rare Met Office red heat warning raises doubts about system resilience and player safety.

Overview

  • The suspension halted all qualifying matches at Roehampton on Wednesday after the tournament's Electronic Line Calling (ELC) system began malfunctioning in the midday heat, forcing players off court.
  • Britain’s Dan Evans was among those stopped mid-match and players were told to leave the courts while officials worked to recalibrate or reboot the ELC.
  • Organisers announced there would be no play before about 13:15 local time as technicians attempted fixes; some reports suggested a possible power-related fault but that remains unconfirmed and under investigation.
  • A rare Met Office red heat warning covered parts of southern and central England with local temperatures in the low- to mid-30s Celsius and forecasts of higher peaks, and Wimbledon uses a Wet Bulb Globe Temperature (WBGT) heat-stress index that can trigger a 10-minute player break when thresholds are met.
  • The incident highlights growing concerns about replacing human line judges with automated systems, the need for tech resilience in extreme weather, and potential scheduling and player-welfare consequences ahead of the main draw.
