A malfunction with Wimbledon 's new electronic line calling system required a point to be replayed during Taylor Fritz's quarterfinal win over Karen Khachanov.

Fritz’s third-set mini-crisis was closely followed by the latest failure of the electronic umpire. Swedish umpire Louise Azemar-Engzell called 'stop' in the opening game of the fourth set on Court One when 'fault' was incorrectly called after a Fritz forehand landed well inside the baseline.

Taylor Fritz recovered from a mid-match lull and reached the Wimbledon semifinals for the first time with a 6-3, 6-4, 1-6, 7-6 (4) victory over Karen Khachanov.
