Wimbledon bosses are “deeply disappointed” by Sunday’s electronic line calling failure but insist they are confident it will not happen again.

Officials blamed human error for the incident at a crucial stage of the fourth-round match between Sonay Kartal and Anastasia Pavlyuchenkova, with the system inadvertently turned off and not flagging that a shot from the British player was out.

Pavlyuchenkova, who would have moved 5-4 ahead had the call been made, was furious with umpire Nico Helwerth for ordering the point to be replayed, accusing him of stealing the game and the tournament of home bias.
