Overview

  • Wimbledon’s new electronic line calling system now covers all 18 match courts and issues automated calls within a tenth of a second.
  • The tournament cut its pool of about 300 line judges down to 80, assigning the remaining officials as match assistants in case of technology failures.
  • British No 1 Jack Draper and former champion Emma Raducanu have flagged specific calls they say misjudged ball marks on the grass.
  • Tournament director Jamie Baker highlighted tour-wide adoption of live line calling and said the system’s reliability allows matches to run later into the evening.
  • Former line judge Pauline Eyre cautioned that removing on-court officials could diminish tennis’s human element and discourage future officiating talent.
