CENTRE COURT, THE ALL ENGLAND CLUB — Anastasia Pavlyuchenkova suggested her British opponent may have received preferential treatment as simmering tensions around Wimbledon ’s use of electronic line calling (ELC) instead of line judges boiled over Sunday, when the technology malfunctioned at a crucial point on Centre Court.

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

Wimbledon organizers have apologized and explained that “human error” was the reason behind the electronic line-calling system being turned off during a match on Sunday.

Horrible” was the word that Anastasia Pavlyuchenkova, the woman who grabbed the first quarterfinal spot at the 2025 Wimbledon Championships, used to describe her ordeal with Lyme disease.

Anastasia Pavlyuchenkova overcame a line-calling technology malfunction on a key point en route to defeating Sonay Kartal 7-6 (3), 6-4 on Sunday to make her second Wimbledon quarterfinal nine years after her first appearance.

Organizers of this year’s Wimbledon have said the latest error with the electronic system was due to a player getting ready to serve while a ball boy was still doing their duties on court.

Sonay Kartal addressed the controversy she experienced with her opponent Anastasia Pavlyuchenkova in the fourth round of Wimbledon. The Brit fell in the tournament's fourth round to the veteran Russian in a match marked by a failed electronic line call at a key moment.

Umpire Nico Helwerth called for a point to be replayed after the ELC system malfunctioned and didn't call Sonay Kartal's out.
