A malfunction with Wimbledon's new electronic line calling system required a point to be replayed during a quarterfinal match between Taylor Fritz and Karen Khachanov on Tuesday. The gaffe occurred during the first game of the fourth set on Court No.

Wimbledon organisers apologise after the electronic line-calling system on Centre Court is turned off in error and misses three calls in one game.

The All England Club, somewhat ironically, is blaming “human error” for a glaring mistake by the electronic system that replaced human line judges this year at Wimbledon.
